9bdcf2a5c6 drm/amd/display: w/a to program DISPCLK_R_GATE_DISABLE DCN35 
[WHY & HOW]
Cursor corruption observed on USBC display with specific system setup with a
reboot. Cursor memory might still in the lightsleep state due to voltage
issue, we need program DISPCLK_R_GATE_DISABLE to avoid this issue only on
DCN35.

223ac8b6f5 drm/amd/display: Remove redundant if conditions 
[WHY]
Coverity analysis flagged the two if conditions in
dcn30_dpp.c and dcn401_dpp.c as DEADCODE since they
are never true, since the variable
'program_prealpha_dealpha' is initialized at 0 and
never chagnes.

[HOW]
Removed the variable 'program_prealpha_dealpha' and
the if conditions.

470679ef33 drm/amd/display: Guard reading 3DLUT registers for dcn32/dcn35 
[Why]
3DLUT is not part of the DPP on DCN32/DCN35 ASIC and these registers
now exist in MCM state.

[How]
Add guards when reading DPP state based on whether the register has a
valid offset.
