What node does this property apply to? Document this in mfd/arizona.txt.

I would like the possible values documented here or a better
education as to what this is because I have no idea if this property
makes sense and I can't read everybody's datasheet. Just because you
have it as platform data doesn't mean it belongs in DT.
