    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

Author: Chris Wilson <chris@chris-wilson.co.uk>

    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

Changelog v1:
This patch fixes a issue that overlay data aren't applied
to real hardware when dpms off goes to on after setcrtc
was requested like below,
    dpms off -> setcrtc -> dpms off -> dpms on
