ACPI: x86: Drop quirk for HP Elitebook

Browse Source 
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.
