There is no need to clean up debugfs manually, it will be done by the
DRM core on device deregistration.

There are two reasons to have the debugfs removed in the early_unregister:
1) Today, registration happens in late_register(), hence to balance the
the call in _dpu_encoder_init_debugfs(), this one is present.
2) In drm_modeset_register_all(), if drm_connector_register_all() fails,
it calls drm_encoder_unregister_all() first which calls early_unregister().
So to balance these out, dont we need to keep it?
