Why would we want to encode the particular way Linux happens to
represent regulators on a MFD into the DT binding? It's not clear that
this is a generic thing (another OS might choose to have a separate
object for each regulator with no parent for example) and the compatible
isn't adding any information we didn't have already knowing about the
parent device.
