[PATCH 22/22] [media] tvp5150: Change default input source selection behaviour

[Marco Felsch]

The default input is still TVP5150_COMPOSITE1, but if the platform
supports DT the default will be changed to the first valid connector.
First in this context means the connector at the lowest port number.
