drm/amd/display: Update TTU properly
[Why]
We need to update TTU properly if DRAMClockChangeWatermark changes. If
TTU < DRAMClockChangeWatermark, we pstate won't be allowed and we will
hang in some PSR cases.
[How]
Update TTU if DramClockChangeWatermark value increases (only if TTU was
dependent on the watermark value on the DRAMClockChangeWatermark value
in the first place).
