[PATCH v3 03/15] acpi/ghes: simplify the per-arch caller to build HEST table

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

The GHES driver requires not only a HEST table, but also a
separate firmware file to store Error Structure records.
It can't do one without the other.

Simplify the caller logic for it to require one function.

No functional changes.

Changes from v10:
- Removed the logic which associates notification and source
  ID. This will be placed on a separate patch.

Changes from v8:
- Non-rename/cleanup changes merged altogether;
- source ID is now more generic, defined per guest target.
  That should make easier to add support for 86.
