[PATCH] convert IDE device drivers to driver-model

* add ide_bus_match() and export ide_bus_type
* split ide_remove_driver_from_hwgroup() out of ide_unregister()
* move device cleanup from ide_unregister() to drive_release_dev()
* convert ide_driver_t->name to driver->name
* convert ide_driver_t->{attach,cleanup} to driver->{probe,remove}
* remove ide_driver_t->busy as ide_bus_type->subsys.rwsem
  protects against concurrent ->{probe,remove} calls
* make ide_{un}register_driver() void as it cannot fail now
* use driver_{un}register() directly, remove ide_{un}register_driver()
* use device_register() instead of ata_attach(), remove ata_attach()
* add proc_print_driver() and ide_drivers_show(), remove ide_drivers_op
* fix ide_replace_subdriver() and move it to ide-proc.c
* remove ide_driver_t->drives, ide_drives and drives_lock
* remove ide_driver_t->drivers, drivers and drivers_lock
* remove ide_drive_t->driver and DRIVER() macro
