tty: Add a full port_close function
Now we are extracting out methods for shutdown and the like we can add a
proper tty_port_close method that knows all the innards of the tty closing
process and hides the lot from the caller.
At some point in the future this will be paired with a similar open()
helper and the drivers can stick to hardware management.
