    Revert "ppdev: use new parport device model"
    
    This reverts commit e7223f18603374d235d8bb0398532323e5f318b9.
    
    It causes problems when a ppdev tries to register before the parport
    driver has been registered with the device model. That will trigger the
    
            BUG_ON(!drv->bus->p);
    
    at drivers/base/driver.c:153. The call chain is
    
      kernel_init ->
        kernel_init_freeable ->
          do_one_initcall ->
            ppdev_init ->
              __parport_register_driver ->
                driver_register *BOOM*
