It's seems really odd that you're adding gpiolib stuff here when you've
also got a separate gpiolib driver.  Possibly this all shouldn't
actually be split up as much as it is - there's also the issue with the
gpiolib driver needing to peer into the interrupt controller.  It might
simplify the code if things were merged more.
