drm/dp: Add drm_dp_max_dprx_data_rate()
Copy intel_dp_max_data_rate() to DRM core. It will be needed by a
follow-up DP tunnel patch, checking the maximum rate the DPRX (sink)
supports. Accordingly use the drm_dp_max_dprx_data_rate() name for
clarity. This patchset will also switch calling the new DRM function
in i915 instead of intel_dp_max_data_rate().
While at it simplify the function documentation/comments, removing
parts described already by drm_dp_bw_channel_coding_efficiency().
v2: (Ville)
- Remove max_link_rate_kbps.
- Simplify the function documentation.
v3:
- Rebased on latest drm-tip.
