Merge tag 'drm-intel-fixes-2013-11-07' of git://people.freedesktop.org/~danvet/drm-intel into drm-next

Bit a bit -fixes pull request in the merge window than usual dua to two
feauture-y things:
- Display CRCs are now enabled on all platforms, including the odd DP case
  on gm45/vlv. Since this is a testing-only feature it should ever hurt,
  but I figured it'll help with regression-testing -fixes. So I left it
  in and didn't postpone it to 3.14.
- Display power well refactoring from Imre. Would have caused major pain
  conflict with the bdw stage 1 patches if I'd postpone this to -next.
  It's only an relatively small interface rework, so shouldn't cause pain.
  It's also been in my tree since almost 3 weeks already.

That accounts for about two thirds of the pull, otherwise just bugfixes:
- vlv backlight fix from Jesse/Jani
- vlv vblank timestamp fix from Jesse
- improved edp detection through vbt from Ville (fixes a vlv issue)
- eDP vdd fix from Paulo
- fixes for dvo lvds on i830M
- a few smaller things all over

Note: This contains a backmerge of v3.12. Since the -internal branch
always applied on top of -nightly I need that unified base to merge bdw
patches. So you'll get a conflict with radeon connector props when pulling
this (and nouveau/master will also conflict a bit when Ben doesn't
rebase). The backmerge itself only had conflicts in drm/i915.

There's also a tiny conflict between Jani's backlight fix and your sysfs
lifetime fix in drm-next.
