Fix regression with DVI and fix warns, and GM45 boot regression.

* tag 'drm-intel-fixes-2014-04-25' of git://anongit.freedesktop.org/drm-intel:
  drm/i915: Move all ring resets before setting the HWS page
  drm/i915: Don't WARN nor handle unexpected hpd interrupts on gmch platforms
  drm/i915: Allow full PPGTT with param override
  drm/i915: Discard BIOS framebuffers too small to accommodate chosen mode
  drm/i915: get power domain in case the BIOS enabled eDP VDD
  drm/i915: Don't check gmch state on inherited configs
  drm/i915: Allow user modes to exceed DVI 165MHz limit
