drm/amd/display: Reorder FCLK P-state switch sequence for DCN32

[WHY?]
In some cases, DCFCLK hardmin requests are not acknowledged by SMU as
the requested clock does not have a compatible ratio with current FCLK,
and it cannot be changed as FCLK P-state is not allowed.

[HOW?]
Allow FCLK p-state change prior to changing DCFCLK hardmin.
