drm/amd/display: Drop reusing drm connector for MST
[why] It is not safe to keep existing connector while entire topology has been removed. Could lead potential impact to uapi. Entirely unregister all the connectors on the topology, and use a new set of connectors when the topology is plugged back on. [How] Remove the drm connector entirely each time when the corresponding MST topology is gone. When hotunplug a connector (e.g., DP2) 1. Remove connector from userspace. 2. Drop it's reference. When hotplug back on: 1. Detect new topology, and create new connectors. 2. Notify userspace with sysfs hotplug event. 3. Reprobe new connectors, and reassign CRTC from old (e.g., DP2) to new (e.g., DP3) connector.
