This is v4 of [1], with the following changes:

- Fix drm_dp_dsc_sink_max_slice_throughput()'s name.
- Use the clearer peak_pixel_rate vs. pixel_clock as the above
  function's parameter.
- Clarify the meaning of peak_pixel_rate for MST tiled displays.
- Fix return value from dsc_throughput_quirk_max_bpp_x16(), in case it's
  not required to limit the BPP.
