drm/i915/dp_tunnel: Query max BW config via link_caps for BW computation

Query the maximum link BW configuration via the link caps interface to
compute the available TBT bandwidth. Unlike the max common link params
used so far for this, the max BW config also accounts for any forced
link parameters.

This makes the max BW link config query uniform across mode validation
and TBT BW calculation, and allows unexporting the
intel_dp_link_caps_max_common_lane_count() helper.

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