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.
