As Clement pointed out, this should be documented in
Documentation/devicetree/bindings/arm/sunxi.yaml

It's part of sunxi/for-next only at this point, and it will go through
a different branch than the H6 DTS, so it would be great to have it in
a separate patch.

If we have an ID pin, then why is the OTG controller set to host?
