Documentation - Csi channels (cam0 or cam1?)

[rraat]

Unfortunalaly documentation is a bit lacking.
As a cm4 module is used the second csi interface (cam1) is available.
The cam1 is a 4-channel interface which allows for a higher bandwidth where cam0 is only 2-channel
From the documentation it isn't clear which interface is used.
Could you please update the documentation to provide clarification of which interface is used?

A schematic showing the cm4 pins used would be awesome

I have updated the document, specifically explained this problem in 2.14, and attached the latest test video:https://www.youtube.com/watch?v=aehOawHklGE

@ThomasVon2021 I missed this video in the README, can you add it to the main readme to help others?
