Pull intel drm fixes from Daniel Vetter:
 "So I heard that proper pull requests have a revert on top ;-) So here
  we go with my usual mid-merge-window pile of fixes.

[ Ed. This revert thing had better not become the "in" thing ]

   Big fix is the duct-tape for ring init on g4x platforms, we seem to
  have found the magic again to make those machines as happy as before
  (not perfect though unfortunately, but that was never the case).

  Otherwise fixes all over:
   - tune down some overzealous debug output
   - VDD power sequencing fix after resume
   - bunch of dsi fixes for baytrail among them hw state checker
     de-noising
   - bunch of error state capture fixes for bdw
   - misc tiny fixes/workarounds for various platforms

  Last minute rebase was to kick out two patches that shouldn't have
  been in here - they're for the state checker, so 0 functional code
  affected.

  Jani's back from vacation, so he'll take over -fixes from here"
