Nicholas Susanto b72a7e0fd0 drm/amd/display: Enabling urgent latency adjustment for DCN35 
[Why]

Underflow occurs when running netflix in a 4k144 eDP + 4k60 setup.
Increasing DCFCLK or urgent latency watermark fixes the issue. Implementing
this workaround for now while we figure out why this is happenning in DCN.

[How]

Enable urgent latency adjustment and match the reference to existing ASIC
that also see increased latency at low FCLK.
