[Why & How] Now the vc_start_slot is controlled at drm side. When we service a long HPD, we still need to run dm_helpers_dp_mst_write_payload_allocation_table() to update drm mst_mgr's relevant variable. Otherwise, on the next plug-in, payload will get assigned with a wrong start slot. Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/2171Signed-off-by:
