mmc: Add nvram hostfw directory

Created an nvram directory to store the hypervisor's NVRAM files.
Create a symlink to that directory for apps like PLDM to access it.
Add a dependency to the symlink service to start before the PLDM
services that would make use of the new NVRAM directory start.

Tested: Verified the directory and symlink got created. Verified the
PLDM services started after the symlink one.

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.

functions: Remove GetObject to check if PLDM is running

In order to check if PLDM is running, the code was subscribing to Name
Owner change and calling GetObject to see if PLDM was running, but PLDM
starts and does not immediately create its Object Manager, therefore
there is a time window when if PLDM starts but hasn't created its Object
Manager, and the openpower service starts, it'll hang forever waiting
for the Name Owner change signal that will not be sent because PLDM
already started.

Instead of calling GetObject, just attempt to run the callback, in this
case setting the bios attribute, and forward the exception if it fails
(due to PLDM not running and the property not existing in D-Bus yet),
so that the openpower service continues to wait. Change the log severity
to informational since setting the bios attribute will fail if PLDM has
not started yet.

Tested: Stopped the PLDM and Entity Manager services and started these
services and the openpower service in various different orders to verify
the openpower service ran when both PLDM and EM had started.

mmc: Add dependency to openpower-update-bios-attr-table.service

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.

mmc: Copy only LID files during update

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

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.

openpower-proc-control to read data for the appropriate system type
since the symlink would be pointing to the right lid file depending on
system type.

No need to hardcode the symlink for HBB, this is done automatically now
based on the JSON file.

Tested:
Verified all element files pointed to the right lid file, ex:

lrwxrwxrwx 1 root root 12 Jul 26 16:08 DEVTREE ->
81e00673.lid
lrwxrwxrwx 1 root root 12 Jul 26 16:08 HBB ->
81e0065a.lid

functions: bios-attr: Add match for PLDM

Add a match to watch for PLDM name owner change to detect when PLDM
starts. The callback would check if the new owner is set, which means
the service started instead of stopped, and then gets the properties
from entity manager to call the function that parse the json file and
sets the bios attr. If the entity manager interfaces are empty, it just
returns and the entity manager callback would take over when entity
manager starts.

This bios attr subcommand is now a vector to be able to return the two
matches, the one for EM and the new PLDM one.

Tested: Verify the bios attr was set when EM and PLDM were stopped and
EM was started then PLDM, and also having PLDM start first then EM.
