Default drm/i915: Sanitize the output registers after resume

This patch is already queued for the next .38 stable release, but I'd
like to go ahead and get it in for the first natty SRU.

SRU Justification

Impact: Graphics corruption after resuming from hiberante on some
machines with Intel GMA 3150 graphics, others potentially affected as
well.

Fix: Upstream patch to force output registers to known state in resume
hanlder

Test case: Hibernate affected machines and observe the display after
resuming.
