ACPI: x86: s2idle: Force AMD GUID/_REV 2 on HP Elitebook 865

commit 3ea45390e9c0d35805ef8357ace55594fd4233d0 upstream.

HP Elitebook 865 supports both the AMD GUID w/ _REV 2 and Microsoft
GUID with _REV 0. Both have very similar code but the AMD GUID
has a special workaround that is specific to a problem with
spurious wakeups on systems with Qualcomm WLAN.

This is believed to be a bug in the Qualcomm WLAN F/W (it doesn't
affect any other WLAN H/W). If this WLAN firmware is fixed this
quirk can be dropped.
