media: dt-bindings: media: ov772x: Document endpoint props



Document endpoint properties for the parallel bus type and
add them to the example.

Specify a few constraints:
- If the bus type is BT.656 no hsync or vsync polarities can be
  specified.
- If the bus width is 10 bits, not data-shift can be applied.
