Not really, it has to happen platform by platform.

I did consider putting all the GPIO descriptors into a radix and
use that internally in gpiolib, but that wasn't easy to do
when I tried it, maybe I just thought backwards.

I would appreciate if drivers for new archs like arm64 would
use only GPIO descriptors from day one. Also if new drivers
only apply a an entirely new machine even. They should just
use descriptors.
