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.
