powerpc/powermac: New windfarm driver for PowerMac G5 (AGP) and Xserve G5
This replaces the old therm_pm72 using the same windfarm infrastructure that was used for other PowerMac G5 models. The fan speeds and sensors should now be visible in the same location in sysfs. The driver is split into separate core modules for PowerMac7,2 (and 7,3) and RackMac3,1, with a lot of the shared code now in the separate sensor and control modules.
