drm/amd/display: ensure committing streams is seamless
[Why]
When transitioning between topologies such as multi-display to single
display ODM 2:1, pipes might not be freed before use.
[How]
In dc_commit_streams, commit an additional, minimal transition if
original transition is not seamless to ensure pipes are freed.
