2025-01-24drm/amd/display: Optimize cursor position updatesAric Cyr
[why] Updating the cursor enablement register can be a slow operation and accumulates when high polling rate cursors cause frequent updates asynchronously to the cursor position. [how] Since the cursor enable bit is cached there is no need to update the enablement register if there is no change to it. This removes the read-modify-write from the cursor position programming path in HUBP and DPP, leaving only the register writes.

2025-01-24drm/amd/display: Add hubp cache reset when powergatingAric Cyr
[Why] When HUBP is power gated, the SW state can get out of sync with the hardware state causing cursor to not be programmed correctly. [How] Similar to DPP, add a HUBP reset function which is called wherever HUBP is initialized or powergated. This function will clear the cursor position and attribute cache allowing for proper programming when the HUBP is brought back up.

[why & how] Remove unnecessary call to REG_SEQ_SUBMIT and REG_SEQ_WAIT_DONE, since those macros are not necessary anymore at the dpp1 set degamma. Those are part of an old implementation.
