[Intel-gfx] [PATCH 1/3] drm/i915: Initialize eDP source rates after per-panel VBT parsing

[Ville Syrjala]

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.

I'm not immediately spotting anything that would consult the link
rate arrays before this, so seems safe enough.
