[media] media: lirc_dev: remove support for manually specifying minor number
All users of lirc_register_driver() uses dynamic minor allocation, therefore we can remove the ability to explicitly request a given number. This changes the function prototype of lirc_unregister_driver() to also take a struct lirc_driver pointer as the sole argument.
