[PATCH 00/15] Prepare GHES driver to support error injection

During the development of a patch series meant to allow GHESv2 error injections,
it was requested a change on how CPER offsets are calculated, by adding a new
BIOS pointer and reworking the GHES logic. See:

https://lore.kernel.org/qemu-devel/cover.1726293808.git.mchehab+huawei@kernel.org/

Such change ended being a big patch, so several intermediate steps are needed,
together with several cleanups and renames.

As agreed duing v10 review, I'll be splitting the big patch series into separate pull
requests, starting with the cleanup series. This is the first patch set, containing
only such preparation patches.

The next series will contain the shift to use offsets from the location of the
HEST table, together with a migration logic to make it compatible with 9.1.
