drm/xe: Restore pci state upon resume

Browse Source 
The pci state was saved, but not restored. Restore
right after the power state transition request like
every other driver.

v2: Use right fixes tag, since this was there initialy, but
    accidentally removed.

Fixes: f6761c68c0 ("drm/xe/display: Improve s2idle handling.")
