Yeah, we have a few mfd drivers whose child drivers registers their
class devices directly under the parent mfd device rather than the
corresponding child platform device.

Since it's done consistently I think you need to update them all if you
really want to change this.

And it may not be worth it since at least in theory someone could now be
relying on this topology.
