clang-format: re-format for clang-18

clang-format-18 isn't compatible with the clang-format-17 output, so we
need to reformat the code with the latest version. The way clang-18
handles lambda formatting also changed, so we have made changes to the
organization default style format to better handle lambda formatting.

See I5e08687e696dd240402a2780158664b7113def0e for updated style.
See Iea0776aaa7edd483fa395e23de25ebf5a6288f71 for clang-18 enablement.

Recover host devtree file if corrupted

This commit addresses the issue where device tree file corruption could
lead to the failure of the BMC to boot up. Corruption of the file may
occur during a kernel panic. In such instances, recovery of the previous
uncorrupted version of the file from the available read-only version is
now implemented.

A PEL is generated indicating the same and the BMC dump is generated.

Tested and working as expected.

mmc: Set clear NVRAM bios attribute during factory reset

During factory reset, instead of calling the PLDM services to delete the
PHYP NVRAM files, set the pvm_clear_nvram bios attribute to Enabled to
signal the hypervisor to clear NVRAM when it starts up.

Add the nvram hostfw directory to the list of directories to preserve
during a factory reset because the NVRAM files would now be cleared by
the hypervisor after reading the bios attribute.

Tested: Verified the pvm_clar_nvram bios attribute was set to Enabled as
part of factory reset. Verified a journal error message was logged if
the attribute did not exist and the rest of the factory reset actions
were executed.

mmc: Add HardwareIsolation service to restart if factory resets

- The HardwareIsolation (daemon) service is dependent on the host partition
to share the host isolated hardware entries through the external
interface (for example Redfish).

- But, If we attempted to do the factory reset then, the host partition
gets deleted and recreated back so due to this the HardwareIsolation
daemon is unable to handle the host partition.

- Fixed the above mentioned issue by restarting the HardwareIsolation daemon.

- Note, start unit won't help if the service is already running like a daemon
so, we need to use restart method for the HardwareIsolation so modified
the code to use a method based on the services that's need to consider
in the host factory reset.

Tested:

- Verified by the host factory reset.

openpower: mmc: physical reset triggers bios reset

The service openpower-bios-factory-reset runs during startup and
calls bios_reset_check. This method determines whether the
factory-reset-toggle gpio has changed since the last reboot and
triggers a bios reset if it has. This decouples the code to check
for bios resets from the code in item_updater_mmc::reset and from
the BMC factory reset code.

the previous value of the environment variable rwreset. Added files
to /media/hostfw and verified that they were removed upon reboot
when the value in reset-gpio-val differed from rwreset.

mmc: Handle missing pnor.toc file

The pnor.toc file is a mboxd implemenation, and therefore will not exist
once the host uses PLDM instead, which uses .lid files instead of pnor
partition files. As part of the transition, the pnor.toc file is being
built into a .lid file for images that do not contain pnor partition
files. Handle this transition by creating a symlink from pnor partition
file to .lid file. This would remain in place until all the PLDM support
from the hostboot side is in place and mboxd is removed.

Tested: Verified rainier powers on and mboxd starts successfully, and
the volatile partition gets cleared.

The openpower-update-bios-attr-table.service creates symlinks to lid
files is the partition files do not exist. The service
openpower-process-host-firmware.service creates symlinks to the well
known firmware name by deleting the base partition file and creting a
symlink. If both services run at the same time, they can interfere,
causing the bios attr service to create a symlink when it's not desired
(it thinks the file doesn't exist but it's because the process host fw
service just deleted it to create its symlink). Add a dependency to
serialize them.

This is one step closer in replacing the PNOR partition files with LID
files:
- During an update, only copy LID files to the read-write directory. The
update-bios-attr-table service will create symlinks from PNOR
partition files to LID files.
- Use the pnor.toc from the read-only directory to get the list of
preserved partitions, since there won't be a pnor.toc file in the
read-write directory anymore. A future commit will read the PLDM file
table to determine which LID files to preserve.
- Preserve the symlink target (LID file) instead of the symlink name
(partition file name), otherwise the symlink gets broken if we copy a
file that was a symlink.

Tested: Verified after code update that all the partition files were
symlinks to a LID file, and a subsequent update preserved the LID files
that correspond to the preserved partitions.

item_updater_mmc: Implement bios factory reset

Implemented the method ItemUpdaterMMC::reset. It clears files in
/media/hostfw/ related to managing console and virtualization
information, then recreates those files using bus calls to service
files. Added checks to obmc-flash-bios so it doesn't cause problems
when its methods are run multiple times. Modified latest services to
allow them to run more than once. Services which depend on the init
service will run after it.

Tested: Created extra files in the directories that the reset method
removes. Called the reset method using busctl. Verified that the
added files were removed and that the removed files that belong were
recreated. Verified that all services called were run.

mmc: Add update-bios-attr-table subcommand

Add the update-bios-attr-table subcommand to update the bios attribute
table with the host firmware well-known names based on system type. The
system type is provided by Entity Manager, and this new subcommand uses
some of the existing infrastructure that the process-host-firmware
subcommand has to determine the system type.

Add a new service file to run this new subcommand so that it can block
waiting for the entity manager interface to appear on D-Bus.

Subsequent commands will add parsing the JSON file to build the bios
attribute string and set the bios attribute property.

mmc: Move process host firmware to own service

The process-host-firmware subcommand waits for the Entity Manager
interface to appear in D-Bus. It's currently run from the mmc-init
script. But if a system does not support Entity Manager, then the init
service never exits, blocking its dependencies like PLDM from starting.

Move the process-host-firmware to its own service file so that if needs
to wait forever, it doesn't interfere with other processes. Need to
start it after the mmc-init so that all the directories are setup before
the symlinks are created.

Tested: Verified on tacoma that the service remains running and PLDM
starts successfully. Verified on rainier that the symlinks are created.
