drm/amd/display: Enable urgent latency adjustments for DCN35
[Why]
Underflow occurs when running Netflix in a 4k144 eDP + 4k60 HDMI FRL
setup. It is caused by latency varying based on the DCFCLK/FCLK state.
[How]
Enable urgent latency adjustment and match the reference to existing
ASIC that also see increased latency at low FCLK.
