This left the driver with an undocumented (and wrong) DT parsing logic, so lets get rid of this code as well until the input connectors support is implemented properly. It's a partial revert due other patches added on top of mentioned commit not allowing the commit to be reverted cleanly anymore. But all the code related to the DT parsing logic and input entities creation are removed.

Physical the TVP5150 has three ports: AIP1A, AIP1B and YOUT. As result of discussion [1],[2] the device-tree maps these ports 1:1. The svideo connector must be conneted to port@0/endpoint@1, look at the Documentation for more information. Since the TVP5150 is a converter the device-tree must contain at least 1-input and 1-output port. The mc-connectors and mc-links are only created if the device-tree contains the corresponding connector nodes. If more than one connector is available the media_entity_operations.link_setup() callback ensures that only one connector is active.

The TVP5150 AVID will be updated if the 'which' field is FORMAT_ACTIVE and the requested selection rectangle differs from the already set one.
