drm/amd/display: Allow Latency Increase For Last Strategy 



[Why]
Playing 1080p video on 4k60 timing uses UCLK DPM5 and mode support
determines that p-state switching is not supported.

[How]
Allow DML to increase latency as the last strategy so strategies such
as VBlank p-state switching may become possible
