drm/i915: Undo "Uncouple render/power ctx before suspending"

Manaul revert of 0cdab21f9a1fca50dd27e488839f5a6578e333b2, just to
remove the call to disable the clock gatings and powerctx before
suspend.

Peter Clifton bisected a suspend failure on his gme45 and found this to
be the culprit. As this was intended to be a fix for a similar suspend
failure for Ironlake (it didn't work), undoing this patch should have no
other side-effects.
