This reverts commit e7223f1860.
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*
