TTY: devpts, don't care about TTY in devpts_get_tty
The goal is to stop setting and using tty->driver_data in devpts code. It should be used solely by the driver's code, pty in this case. First, here we remove TTY from devpts_get_tty and rename it to devpts_get_priv. Note we do not remove type safety, we just shift the [implicit] (void *) cast one layer up. index was unused in devpts_get_tty, so remove that from the prototype too.
