media: partial revert of "[media] tvp5150: add HW input connectors support"
Commitf7b4b54e63("[media] tvp5150: add HW input connectors support") added input signals support for the tvp5150, but the approach was found to be incorrect so the corresponding DT binding commit82c2ffeb21("[media] tvp5150: document input connectors DT bindings") was reverted. 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.
