It's still pretty yucky in that case to scan the device-tree to convert
it into some kind of fugly board info ... I'd rather have the end
drivers that actually use those GPIOs scan the device-tree directly.

But then, I'm not a believer in generic drivers for things like GPIOs,
i2c devices, etc.. :-)
