This is the first step needed to get the snapper codec working on those machines. The second step is to enable the corresponding I2S device and its clock. Tested on machines where the snapper codec was already working, a G4 PowerBook and a PowerMac9,1 with a Shasta based macio. The PowerMac7,2/7,3 with a K2 based macio can now also play sound.
