It looks like DT already supports the generic case for GPIO; each GPIO
reference is of the form:

<&gpio 69 0>

and so each GPIO has a "parent" specified, and hence can come from a
different controller.

For drivers, this is all completely hidden by of_get_gpio().

I imagine we'd just use the same pattern for pinmux. This would both
support the general case, and end up being consistent with how GPIOs
already work, so this seems like a win both ways.

Ah right. I had not seen the gpio binding yet, so that definitely works.
