radeon: fix pll/ctrc mapping on dce2 and dce3 hardware
This fix black screen on resume issue that some people are
experiencing. There is a bug in the atombios code regarding
pll/crtc mapping. The atombios code reverse the logic for
the pll and crtc mapping.
agd5f: drop unnecessary crtc id check, cc stable in case
we miss 3.7.

- Unbreak mbp retina, this time with a much more fine-grained approach
(since the previous "completely ignore edp vbt bpp value" regressed some
machines even after fixing a bug in our dp bw code).
- Disable cloning on sdvo. It just doesn't work (yeah took us a while to
figure out), leading to jittery outputs in the best case.
- Revert rc6 for ilk again. It seems to help a few of the gpu hang
reporters at least, and it's definitely the best we've got.
Head-against-the-wall-banging is still ongoing for what really breaks
(and how we can reproduce the non-rc6 hangs and how to reproduce on
gen4).

Even with the cumulative set of ilk w/a, rc6 is demonstrably still

it again until it is stable.

drm/i915: disable rc6 on ilk when vt-d is enabled
Note: The situation around the gen4/5 gpu hangs that cropped up in 3.7
is rather strange. Most useful bisects have lead to

Date: Mon Aug 20 11:40:46 2012 +0200
drm/i915: Track unbound pages
or even later commits that affect the gem bo recycling, which all is
way past the point where we re-enabled rc6. But somehow
reverting/disabling those commits doesn't help, but disabling rc6 at
least helps for many hangs on ilk. Obviously it doesn't change
anything at all on gen4, and there are still strange issues left on
gen5 (which we unfortunately can't readily reproduce).
Also, the error_state signature of the hangs which can be fixed with
this patch look remarkably different to those which seem to be
unaffected by the rc6 settings: The rc6 hangs are in the ring,
somewhere in the MI_FLUSH/PIPE_CONTROL sequence to make ilk coherent,
wheras all the other hangs tend to be at a random point in the middle
of the user batch. So it could also be that we have different issues.
Until we grow more clue, this at least helps some users.

Move encoder's dpms updating into exynos_drm_encoder_commit
function because when crtc's dpms is updated, encoder's dpms
is updated also. This would induce the issue that encoder

Changelog v1:
This patch fixes a issue that overlay data aren't applied

dpms off -> setcrtc -> dpms off -> dpms on
For this, it makes encoder's dpms to be updated when
