powerpc/powermac: Make auto-loading of therm_pm72 possible
The therm_pm72 driver, used on the PowerMac G5 range, cannot be auto-loaded, since the driver itself creates both the device node and the driver instance. Moving the device node creation to the platform setup code and adding the necessary MODULE_DEVICE_TABLE() information allows the driver to be automatically loaded by udev on any semi-modern distribution. It "fixes" a major source of problem on G5 machines where the driver wasn't explicitely loaded by default, and the system would automatically shutdown under load. Tested on an Xserve G5.
