From: Yazen Ghannam <yazen.ghannam@xxxxxxx>
ACPI defines a number of instructions to use for triggering errors. However
we are currently removing the address resources from the trigger resources
for only the WRITE_REGISTER_VALUE instruction. This leads to a resource
conflict for any other valid instruction.
Remove the WRITE_REGISTER_VALUE instruction check to fix the resource
conflict with other instructions.
Fixes: b4e008dc53a3 ("ACPI, APEI, EINJ, Refine the fix of resource conflict")
