nubus: Call bus_register unconditionally
Loading a NuBus driver module on a non-NuBus machine triggers the BUG_ON(!drv->bus->p) in driver_register(), because bus_register() was not called, because it is conditional on MACH_IS_MAC. Fix the crash by calling bus_register() unconditionally. Call it from a postcore_initcall(), like other busses do. Hence, the bus type is available for device_register(), which happens in a subsys initcall, and for driver_register(), which happens in a device or module initcall.
