Previously ACPI PM1A register info was hardcoded to 0 in HV for generic boards, but SOS still can know the real PM1A info so the system would hang if user trigger S3 in SOS. Enabling PM1A register info fixup will let HV be able to intercept the operation on PM1A and then make basic function of S3 work for all boards; Tracked-On: #2291 Signed-off-by: Victor Sun <victor.sun@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
