GHES handles the PCI Express Error Section and also the Compute Express
Link (CXL) Protocol Error Section. Two of its functions depend on the
APEI PCIe AER logging/recovering support (ACPI_APEI_PCIEAER).

Make GHES select ACPI_APEI_PCIEAER and remove the conditional
compilation from the body of two static functions that handle the CPER
Error Sections mentioned above.

Hi Fabio,

I'm not seeing a justification here for the change and there may be
APEI platforms without PCI support.  So is this just to simplify things or
is there a functional reason that it is necessary?

I have the same worry, embedded system with ACPI support may don't have
PCI. And for APEI, AER is one of the error type and optional.

Thanks
