ACPI, APEI, EINJ: Subtract any matching Register Region from Trigger resources
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.
Check that the instruction is less than or equal to the
WRITE_REGISTER_VALUE instruction. This allows all valid memory access
instructions and protects against invalid instructions.
