Merge tag 'drm-intel-fixes-2015-08-14' into drm-intel-next-fixes

Backmerge drm-intel-fixes because a bunch of atomic patch backporting
we had to do lead to horrible conflicts.

Conflicts:
	drivers/gpu/drm/drm_crtc.c
Just a bit of context conflict between -next and -fixes.
	drivers/gpu/drm/i915/intel_atomic.c
	drivers/gpu/drm/i915/intel_display.c
Atomic conflicts, always pick the code from -next.
