drm: rcar-du: Remove i2c slave encoder interface for hdmi encoder
The hdmi output in rcar-du uses the i2c slave encoder interface to link to the adv7511 encoder chip. The kms driver creates encoder and connector entities that internally uses the drm_encoder_slave_funcs ops provided by the slave encoder driver. Change the driver such that it expects a bridge entity instead of a slave encoder. The hdmi connector code isn't needed anymore as we expect the adv7511 bridge driver to create/manage the connector. Note that the kms driver still expects a connector node for hdmi to be present in DT. This node has no connection to the connector created by the bridge driver.
