The hiomapd repo is used by IBM, and includes openpower-power specific

openpower-pnor-code-mgmt repo that Adriana maintains relies on this
virtual pnor implementation.

Promote Adriana to owner to continue the maintenance of the hiomapd repo
especially the virtual pnor piece, who she was one of the developers and
main reviewers of the code.

Add Ninad as reviewer as he'll be implementing some of the upcoming
changes to the code.

vpnor: Look for files in rw directory first

IBM systems running PLDM create lid files for the host content instead
of PNOR partition files:
```

vpnor: Look for files in rw directory first

IBM systems running PLDM create lid files for the host content instead
of PNOR partition files:
```
https://github.com/openbmc/pldm/blob/master/oem/ibm/configurations/fileTable.json
```

In order to continue to support mboxd (hiomapd), symlinks with the PNOR
partition file names are created to point to the lid files:
https://gerrit.openbmc.org/c/openbmc/openpower-pnor-code-mgmt/+/45249

Since these symlinks are created at runtime, they can only be created in
the read-write directory.
Update the mboxd (hiomapd) code to look at the rw directory first, since
in general the code searches in patch directories first to allow
overrides. Then if the partition files are not found default to the
read-only directory.

The symlinks are created prior to mboxd starting via a Before dependency
in the openpower service file:
```
https://github.com/openbmc/openpower-pnor-code-mgmt/blob/master/mmc/openpower-update-bios-attr-table.service#L6
```

Tested: Verified mboxd started successfully in a p10bmc and witherspoon
system.

resolve stricter warnings

In order to convert this repository to Meson, we need to make it
compile under `warning_level=3`. Fix a number of warning classes
across the repository or disable them.

Some fixes are:

* Add missing header files.
* Fully initialize structs as necessary.
* Add `__attribute__((unused))` on parameters as necessary.
* Fix comparisons between signed and unsigned.
* Fix printf specifiers as necessary.
* Avoid case-fallthrough.
* Remove if conditions which are always true.

Some warnings would require extensive code changes, due to their
pervasive use, and so are disabled at a per-file level:
* `-Wpointer-arith`
* `-Wunused-result`

The function is already returning a const so the declaration of the
variable as a const is redundant (and no longer allowed by the compiler)

format-code: Fix formatting failures

There's a lengthy comment in the custom script as to why it needs to
exist, and given it does, make it work.

At some point the build scripts started passing the directory whose code
should be formatted as the first argument to format-code.sh[1].

When format-code.sh is invoked, the working directory remains the
workspace directory, so make our custom script change into the repo in
order for the git commands to work.

vpnor: Use the partition in rw if it exists

Look for the partition file in the rw directory first as the default.
This allows mboxd to support a single writable directory for the case
where the partition files (including the read-only ones) need to be
modified at runtime by the BMC, for example to support two different
configurations of a system using the same firmware image.

Tested: Enabled debug traces to check where the read and write requests
were being fulfilled from and copied some partition files to
the patch directory:
On witherspoon, verified the reads/writes were done on the patch
directory for the files that existed there, and reads were
fulfilled from the ro dir, and writes from the rw dir.
On rainier where all partitions exist in the rw dir, verified
the reads/writes were done on the patch dir for the files that
existed there, and reads/writes were done to the rw dir. For the
HB_VOLATILE partition that gets erased, the ro dir was then used
to read after it was deleted from the rw dir.
