Just tiny regression fixes here:
- Two fixes to fix sdvo hotplug which broke in the hpd storm detection
  work.
- One fix to patch-up the sdvo lvds regression fixer from the last pull -
  we need to prefer the vbt mode over edid modes.

* tag 'drm-intel-fixes-2013-06-11' of git://people.freedesktop.org/~danvet/drm-intel:
  drm/i915: prefer VBT modes for SVDO-LVDS over EDID
  drm/i915: Enable hotplug interrupts after querying hw capabilities.
  drm/i915: Fix hotplug interrupt enabling for SDVOC
