From: Ville Syrjälä <ville.syrj...@linux.intel.com>
The power sequencer has bits to allow DP C to be used for eDP.
Currently we assume this will never happen, but I guess it could
theoretically be a thing. Make the code do the right thing in that
case, and toss in a MISSING_CASE() for any other port.
