Add ADB support. This provides support for the external ADB bus on the PowerMac

Browse Source 
G3 as well as the internal ADB keyboard and mice in PowerBooks and iBooks. This
also brings in Mac GPIO support, for which we should eventually have a better
interface.

Obtained from:  NetBSD (CUDA and PMU drivers)
