Personally I think the pinctrl settings can stay. Their configuration is part
of the hardware and not subject to the binding of the device using them.
And of course, the change to support them is already pending, with the binding
itself already in the mfd tree.
So it doesn't matter to much if they're in there already or not, as we'll
hopefully soon make use of them anyway.
