drm/amd/display: Run full global validation in dc_commit_state
[Why] Dynamic link encoder assignment expects that it can modify DC current_state and the links associated with the incoming state when performing full validation. This does not align with our actual synchronization constraints in DM's atomic_check. [How] Since link encoder assignment only happens as part of full validation we can just use fast validation as part of atomic_check instead. This satisfy's DC interface requirements and skips the DML calculations needed for pipe programming - hopefully speeding up things a little bit to offset the cost of double validation during stream modification. We already do this as part of dc_commit_updates_for_stream() with validate_bandwidth(), so extend this to dc_commit_state() as well.
