[PATCH v5 01/10] drm/xe/pm: initialize the device's system wakeup capabilities

[Vinod Govindapillai <vinod.govindapillai@intel.com>]

NVL+ XE devices are capable of generating PME from HPDs. Enable
the device as a wakeup device so the display hotplugs can
generate PM PME events and can invoke pm runtime resume routine.
