Right, so that is something the aggregator will actually do since it
creates a whole new GPIO chip.

That feels iffy though because aggregator is really heavyweight and was never
used for this purpose (it's more of a GPIO counterpart to a hierarchical
interrupt chip) and the gpio/interrupt-map nexus is really lightweight.
