From: Ville Syrjälä <ville.syrj...@linux.intel.com> VLV can have eDP on either port B or C, or even both. Based on the VBT spec, intel_dpd_is_edp() should work on VLV too, assuming we check the correct ports.
So instead of hardcoding port D, rename the function to intel_dp_is_edp() and pass the port as a parameter, and use it on VLV ports B and C.
