    smscsuperio: map interrupt in smscsuperio_enable_serial()
    
    This is a stopgap for when you use SUPERIO_SMSC_SMSCSUPERIO and the
    interrupt is unmapped at reset, but for whatever reason the chip is
    inaccessible in smscsuperio/superio.c::enable_dev() and thus the
    devicetree.cb IRQ information is not applied in ramstage and then
    serial console output fails to work for more than the UART FIFO depth
    in the OS.
