drm/amd/display: Update dummy P-state search to use DCN32 DML

Browse source

[Why]
Current DCN3.2 logic for finding the dummy P-state index uses the
DCN3.0 DML validation function instead of DCN3.2 DML.

This can result in either unexpected DML VBA values, or unexpected
dummy P-state index to be used.

[How]
Update the dummy P-state logic to use DCN3.2 DML validation function.
