Subject: [PATCH 1/3] drm/i2c: tda998x: Unregister the connector in the unbind function.

tda998x uses drm_connector_register() in the .bind function that
needs to be balanced with a drm_connector_unregister() in the .unbind.
Otherwise dangling sysfs entries are left behind and future rebinds
will fail.
