This also cleans ups some errors in the binding: The compatible string description suggested that "mmp" in "mrvl,mmp-twsi" is to be substituted with a processor model, which wouldn't be a right thing to do and indeed nobody seems to have been doing that. There also was "Recommended properties" section that included optional as well as mandatory properties. Missing mandatory properties were added to the example.
