[Intel-gfx] [PATCH 5/8] drm/i915: Init infoframe vfuncs for DP encoders as well

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

DP ports may want to use the video DIP for SDP transmission, so let's
initialize the vfuncs for DP encoders as well. The only exception is
port A eDP prior to HSW as that one doesn't have a video DIP instance.
