drm/i915: get a runtime PM ref for the deferred GT powersave enabling
At least on VLV but probably on other platforms too we depend on RC6
being enabled for RPM, so disable RPM until the delayed RC6 enabling
completes.
v2:
- explain the reason for the _noresume version of RPM get (Daniel)
- use the simpler 'if (schedule_work()) rpm_get();' instead of
'if (!cancel_work_sync()) rpm_get(); schedule_work();'
