From: Ville Syrjälä <ville.syrj...@linux.intel.com>
We'll need to know the VBT panel_type before we can determine the
maximum link rate for eDP. To that end move
intel_dp_set_source_rates() & co. to be called after the per-panel
VBT parsing has been done.
intel_dp_mst_encoder_init() depends on the source rates so we'll
have to do it a bit later as well.
v2: Fix the intel_dp_mst_encoder_init() oops
