Add a new interface for drivers to create a group device. Via the old interface ccwgroup_create_from_string we would create a virtual device in a way that only the caller of this function would match and bind to. Via the new ccwgroup_create_dev we stop playing games with the driver core and directly set the driver of the new group device. For drivers which have todo additional setup steps (like setting driver_data) provide a new setup driver callback.
