Public bug reported:

Current i915 driver (4.2) does not support VGA output on SKL. It needs a
bunch of cherry-picks and some backports. Some are not applied upstream
yet, but are being tested to meet OEM schedule..

 drm/i915/skl: Enable DDI-E
 drm/i915/skl: Adding DDI_E power well domain
 drm/i915: Adding break for one case
 drm/i915/skl: DDI-E and DDI-A shares 4 lanes.
 drm/i915: Enable HDMI on DDI-E
 drm/i915: eDP can be present on DDI-E
 drm/i915/skl: enable DDI-E hotplug
 drm/i915: Set alternate aux for DDI-E
 drm/i915: Set power domain for DDI-E
 drm/i915: Handle HPD when it has actually occurred
 drm/i915: abstract away platform specific parts from hpd handling
 drm/i915: simplify condition for digital port
 drm/i915: merge the two hpd loops in intel_hpd_irq_handler to one
 drm/i915: put back the indent in intel_hpd_irq_handler
 drm/i915: simplify conditions for skipping the 2nd hpd loop iterations
 drm/i915: add for_each_hpd_pin to iterate over hotplug pins
 drm/i915: group all hotplug related fields into a new struct in dev_priv
 drm/i915: reduce indent in intel_hpd_irq_handler
 drm/i915: reduce duplicate conditions in i9xx_hpd_irq_handler
 drm/i915: reduce indent in i9xx_hpd_irq_handler
