Rework mgag200_regs_init() and mgag200_mm_init() into device preinit and init functions. The preinit function, mgag200_device_preinit(), requests and maps a device's I/O and video memory. The init function, mgag200_device_init() initializes the state of struct mga_device. Splitting the initialization between the two functions is necessary to perform per-model operations between the two calls, such as reading the unique revision ID on G200SEs.
