Use Startech 1to3 DP hub to do some mst hotplug tests and find some
light up issues.
1. ACT polling timeout:
Which is due to we didn't update DPCD payload table but still try
to send ACT and polling for "ACT Handled" bit
2. Not all monitors light up:
Due to we wrongly set unavailable VCP ID for new streams
Wayne Lin (2):
drm/dp_mst: Do not set proposed vcpi directly
drm/dp_mst: Avoid to mess up payload table by ports in stale topology
