[PATCH 7/8] [media] tvp5150: document input connectors DT bindings

[Javier Martinez Canillas <javier@osg.samsung.com>]

The tvp5150 decoder has different input connectors so extend the device
tree binding to allow device tree source files to define the connectors
that are available on a given board.

 video port, in accordance with the video interface bindings defined in
