drm/amd/display: Optimize subvp and drr validation

Browse source

Two issues existed:
1) Configs that support DRR, but have it disabled will fail subvp+vblank
validation incorrectly. Use subvp+vblank path for this case.
2) Configs that support DRR and have it enabled can use higher voltage level
than required if they also support subvp+vblank. Use lowest supported voltage
level for this case.
