drm/amd/display: Fix DPREFCLK override when SMU isn't present or ready for DCN315

Browse source

[Why]
If SMU has not loaded properly or is not present in a test environment,
then the DPREFCLK is overridden with an invalid value.

[How]
Add an SMU present check and shift the override below the check.
