acpi: Bump FADT to revision 6
Some of the revision 4 FADT fields were already updated to ACPI
spec revision 6, but not all of them. In addition the advertised
FADT revision was 3.
Implement all fields as defined in version 6 and bump the advertised
FADT revision to 6.
Also set all used access_size fields and x_gpe0_blk to sane values
as Windows 10 verifies those fields starting with FADT revision 5.
Fixes: https://ticket.coreboot.org/issues/109
Tested on Windows 10.
