[Intel-gfx] [PATCH 1/2] drm/i915: Move intel_dp->prepare_link_train assignment into ddi code

[Ville Syrjala]

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

It's a bit silly to go through intel_dp.c to assign the
prepare_link_train vfunc for ddi platforms when we can just
assign it directly from intel_ddi.c.
