Merge tag 'topc/core-stuff-2014-05-05' of git://anongit.freedesktop.org/drm-intel into drm-fixes

Some more i915 fixes. There's still some DP issues we are looking into,
but wanted to get these moving.

* tag 'topc/core-stuff-2014-05-05' of git://anongit.freedesktop.org/drm-intel:
  drm/i915: don't try DP_LINK_BW_5_4 on HSW ULX
  drm/i915: Sanitize the enable_ppgtt module option once
  drm/i915: Break encoder->crtc link separately in intel_sanitize_crtc()
