ACPICA: Permanently set _REV to the value '2'.
ACPICA commit 7af00219681ab35ebe57d64a9189fd04a5a026d8
Windows uses a value of 2, and has no plans to ever change this. So, _REV is
essentially useless for its primary purpose.
Worse, some BIOS vendors have used the difference in _REV values between
Windows and ACPICA to indicate which one is running.
It has been decided by the ACPI community to deprecate this method, and return
1 for ACPI 1.0 (32-bit integers) and 2 for ACPI 2.0 and greater (both 32-bit
and 64-bit integers.
ACPICA is changed to reflect this.
