- Remove assigned-clock-rate property and set mdp clk during resume sequence.
- Add fixes tag.

Changes in v3:
- Remove extra line after fixes tag.(Stephen Boyd)
- Add similar changes for sc7180, sdm845 which uses opp table for voting mdp clk.(Stephen Boyd)
- Drop patch: "drm/msm/disp/dpu1: set mdp clk to the maximum frequency in opp table"

Changes in v4:
- Add similar change for sm8250.(Dmitry)

Changes in v5:
- Add change to set mdp clk to max frequency in opp table during mdp probe/bind.

Changes in v6:
- Remove change log in dt patch.
- Fix the leak reference for opp by adding dev_pm_opp_put. (Dmitry)
