drm/amd/display: Add trigger FIFO resync path for DCN35


[Why]
FIFO error can occur if we don't trigger a DISPCLK change after
touching K1/K2 dividers. For 4k144 eDP + hotplug of USB-C DP display
we see FIFO underflow.

[How]
We have the path to trigger the resync as the workaround in
DCN314/DCN32, it just needs to be ported over to DCN35.
