From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Reduce the 'intel_dp' stuff a bit by introducing local
cpu_transcoder variables.
Ideally I'd like the whole PSR code to stop using intel_dp
except during a full modeset, but dunno yet if that's
possible. But the less 'intel_dp' we have sprad around
the easier that should be to figure out eventually.
