The commit 92bab9142456 ("drm/msm: less magic numbers in
msm_mdss_enable") reworked the static UBWC setup to replace magic
numbers with calulating written values from the SoC/device parameters.
This simplified adding new platforms.
However I did not estimate that the values would still be cryptic and
would be C&P-sted instead of being determined from the vendor DT. Some
of the platform (sc8180x) completely missed this setup step.

This series attempts to rework the static UBWC setup to be both
manageable and hopefully easier to write.

Changes since RFC:
- Merged sm6115 fixup patch into the main patch, since only the comment
  was incorrect
- Moved reading HW revision and UBWC decoder version to the error case
  only

Dmitry Baryshkov (3):
  drm/msm/mdss: convert UBWC setup to use match data
  drm/msm/mdss: add data for sc8180xp
  drm/msm/mdss: add the sdm845 data for completeness
