[PATCH v2 16/20] drm/bridge: tda998x: Remove component support

["Kory Maincent (TI.com)" <kory.maincent@bootlin.com>]

The tilcdc driver no longer uses the component framework to bind the
tda998x bridge driver. The component bind/unbind operations and the
encoder initialization code are now dead code and can be safely removed.
