misc i915 fixes.

* tag 'drm-intel-fixes-2015-05-08' of git://anongit.freedesktop.org/drm-intel:
  drm/i915: Drop PIPE-A quirk for 945GSE HP Mini
  drm/i915: Sink rate read should be saved in deca-kHz
  drm/i915/dp: there is no audio on port A
  drm/i915: Add missing MacBook Pro models with dual channel LVDS
  drm/i915: Assume dual channel LVDS if pixel clock necessitates it
