After assisting dt-binding reviews in the past, I get the impression
that "mfd" in a compatible string name is not going to be accepted.
The bindings should be OS-independent, MFD is a Linux implementation.
In principle this could be just "airoha,an8855" for the entire SoC.

And the node name could be just "soc at 1".

I hope it's not mandatory to duplicate in the example also the bindings
of the children, especially since you link to their own schemas.
