Updates to x86/include/arch/acpi.h for use in fadt.c
- Added a union to identify the byte that was reserved in the
Generic Address Structure from ACPI 2.0 to ACPI 2.0b as the
Access Size byte for ACPI 2.0c to ACPI 5.0
- Added various #defines for use in the FADT
- Added a couple of comments for the #endifs
