TTY: tty3270, add tty install
This has two outcomes: * we give the TTY layer a tty_port * we do not find the info structure every time open is called on that tty In this case ->install is the only thing we want to do. We do not need ->open at all. See the tty->count > 1 check. And since we take a reference in ->install, we need also ->cleanup to drop the reference to a view. Final note, see that we leave raw3270_find_view in place. It is because views are removed even from module_exit.
