drm/amd/display: Speed up DML fast_validate path
[Why]
Iterating over every voltage state when we need to validate thousands of
configurations all at once (i.e. display hotplug) can take a significant
amount of time.
[How]
Check just the highest voltage state when fast_validate is true to
verify whether the configuration can work at all, then do a proper
validation including all voltage states later when fast_validate is false.
