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.
