[PATCH 18/22] dt-bindings: media: sun6i-a31-csi: Add ISP output port

Some Allwinner devices come with an Image Signal Processor (ISP) that
allows processing camera data to produce good-looking images,
especially from raw bayer representations.

The ISP does not have a dedicated capture path: it is fed directly by
one of the CSI controllers, which can be selected at run-time.

Represent this possibility as a graph connection between the CSI
controller and the ISP in the device-tree bindings.
