From: Ville Syrjälä <ville.syrj...@linux.intel.com>
Since we now populate encoder->devdata for all DP capable
platforms we can consult it directly during the eDP
connector init instead of taking a detour via some global
list/array.
Unfortunately we can't quire get rid of
intel_dp_is_port_edp() since it's still used by the higher
level ilk/vlv/chv output setup code.
