drm/i915/dp: Query max BW config via link_caps during mode validation

Browse source

Query the maximum link BW configuration during mode validation and MST
link probing directly from intel_dp_link_caps_get_max_bw_config(),
instead of using the intel_dp_max_link_rate() and
intel_dp_max_lane_count() helpers.

This makes the max BW link config query uniform across mode validation
and TBT BW calculation, and allows unexporting the
intel_dp_max_link_rate()/intel_dp_max_lane_count() helpers.

v2: Use the max BW link configuration, instead of the max link limits.
