serial: sc16is7xx: add driver name to struct uart_driver

Make sure that the driver name is displayed instead of "unknown" when
displaying the driver infos:

Before:
    grep ttySC /proc/tty/drivers
    unknown              /dev/ttySC    243 0-7 serial

After:
    grep ttySC /proc/tty/drivers
    sc16is7xx            /dev/ttySC    243 0-7 serial
