[PATCH v7 00/10] ACPI: APEI: share GHES CPER helpers and add DT FFH provider

[Ahmed Tiba]

This is v7 of the GHES refactor series. Compared to v6, it addresses
the Sashiko-reported issues including pre-existing ones and fixes
the ACPI-disabled cper-x86 build break.

The DT firmware-first CPER provider is intended for the upstream zena-css
platform. Validation so far has been on FVP.

Changes in v7:
- Address Sashiko-reported issues for this series, including pre-existing ones.
- Fix pre-existing CPER header overflow validation in cper.c.
- Fix AER recovery leak when no pci_dev is found.
- For DT provider: serialize pool init, return IRQ_NONE on empty status,
  add OF_RESERVED_MEM dependency, and harden status length checks.
- Include <asm/acpi.h> in cper-x86.c for ACPI-disabled builds.
