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