Convert the binding to DT schema format.

The sub-functions of this MFD device do not have their own compatible
string and are thus described directly in the MFD binding document
after being converted to YAML.

I expect this will go through your tree and I don't need an
immutable branch, since all further fixes on the binding would
go into your tree anyways.

Also please note, that I put you in as maintainer, since the
original people working on max8925 long vanished and you are the
maintainer of MFD (and backlight). Please tell me if you have a
better suggestion.

Greetings,
