Normally we do this in drm_mode_config_cleanup. But analogix dp's
connector is allocated in bind, and freed after unbind. So we need
to destroy it in unbind to avoid further access.

Not related to the patch, but what about bridge, above it is only
disabled, but not detached, encoder cleanup code should do it but it is
also missing.
