Merge tag 'drm-intel-next-fixes-2015-09-02' of git://anongit.freedesktop.org/drm-intel into drm-next

i915 display fixes headed for v4.3. Mostly SKL, but some regression
fixes too.

* tag 'drm-intel-next-fixes-2015-09-02' of git://anongit.freedesktop.org/drm-intel:
  i915: Set ddi_pll_sel in DP MST path
  drm/i915: Don't use link_bw for PLL setup
  drm/i915: Preserve SSC earlier
  drm/i915/skl: Adding DDI_E power well domain
  drm/i915: eDP can be present on DDI-E
  drm/i915/skl: Enable DDI-E
  drm/i915: Enable HDMI on DDI-E
  drm/i915: apply the PCI_D0/D3 hibernation workaround everywhere on pre GEN6
  drm/i915: Check DP link status on long hpd too
  drm/i915: set CDCLK if DPLL0 enabled during resuming from S3
