[PATCH v5 0/1] acpi: apei: Bug fix to enable APEI support for ARMv8

[Loc Ho]

v5:
* Remove the patch set 1/2 as it was accepted
* Fix the signed-off-by using Co-authored-by

v4:
* Update patch commit log for gsi.c patch
* Make change to be 80 column aligned

v3
* Change the title of the patch to reflect the patch
* Completely dropped the driver. Instead, move completely to the FW by
  accessing the GIC directly.
* Fix a bug with function acpi_gsi_to_irq
* Enable APEI multiple GHES source to share an single external IRQ

v2
* Make all code more generic naming
* Still waiting for comment from Linaro folks on APEI
