There was a quirk in `acpi/x86/s2idle.c` for an HP Elitebook G9 platforms to force AMD GUID codepath instead of Microsoft codepath. This was due to a bug with WCN6855 WLAN firmware interaction with the system. This bug is fixed by WCN6855 firmware: WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.23 Remove the quirk as it's no longer necessary with this firmware.
