[PATCH 04/14] drm/i915/ddi: For an active output call the DP encoder sync_state() only for DP

[Imre Deak]

If the DDI encoder output is enabled in HDMI mode there is no point in
calling intel_dp_sync_state(), as in that case the DPCD initialization
will fail - as expected - with AUX timeouts. Prevent calling the hook in
this case.
