drm/amd/display: apply vmin optimization even if it doesn't reach vmin level

Browse source

[why]
Based on power measurement result, in most cases when display clock
is higher than Vmin display clock, lowering display clock using
dynamic ODM will improve overall power consumption by 0 to 4 watts
even if we can't reach Vmin.

[how]
Allow vmin optimization applied even if dispclk can't reach Vmin.
