drm/amd/display: Enable urgent latency adjustment on DCN35

[Why]

Urgent latency adjustment was disabled on DCN35 due to issues with P0
enablement on some platforms. Without urgent latency, underflows occur
when doing certain high timing configurations. After testing, we found
that reenabling urgent latency didn't reintroduce p0 support on multiple
platforms.

[How]

renable urgent latency on DCN35 and setting it to 3000 Mhz.

This reverts commit 3412860cc4c0c484f53f91b371483e6e4440c3e5.
