Hi Thomas

It would be nice to add pinctrl to this. The likely pins are defined
in kirkwood-6281.dtsi. dreamplug does not define hogs for these pins,
so its relying on grub setting them up and nothing changing them.

Maybe Jason can do this?

There is probably a header file which can be removed as well.
