drm/i915: add pme_enabled() to the parent interface

Browse source

PME capabiliy need to be assessed very early during runtime suspend
routine to avoid resetting HPDs during IRQ resets. As display
runtime pm routines are being executed in the independent intel
display driver entry points, we need to have independent access
to the pme status as well. Add a provision to query the optional
pme_enabled to the parent interface so that it could be called
independently based on xe/i915's pme_enabled() implementation.
