serial: 8250: extract serial8250_startup_special()

Browse source

Let the serial8250_do_startup() code handle the special ports (16C950,
DA830, RSA) startup in a separate function:
serial8250_startup_special().

And instead of multiple if-else-if, use switch-case. So that it can be
easily checked for PORT_RSA now too.
