Every port in the system has to have its struct tty_port counterpart.

/me looked into the code

OMG. It contains a true copy of serial_core!

In the beginning (to remove the BROKEN flag), what it needs is struct
tty_port to be added to struct sb_uart_info. It obviously needs
tty_port_init + tty_port_destroy at appropriate places. Then it needs
tty_register_device to be switched to tty_port_register_device.

Finally, having the tty_port, all tty flipping functions take the
tty_port, not tty_struct (the build errors reported). This is easy while
you have a tty_port.

In the long term, it needs to get rid of the all the pseudo-uart* stuff
(the copy of serial_core) and use only tty layer+tty_port helpers.
