To handle error trigger table correctly, memory region must be
removed from request region. We ever have a patch to do this
work (commit id: b4e008dc5) but at that time ACPI5 is unrevealed
so this option is missed. When using EINJ table on an ACPI5
enabled machine, we get following error:

APEI: Can not request [mem 0x526b80000-0x526b80007] for APEI EINJ
Trigger registers

This patch fixes this issue.
