  Log:
  Default to a interrupt router that returns an invalid interrupt.
  Otherwise, busses that implement the pcib interface that forget to
  implement pcib_route_interrupt would return EIO, which the caller
  interprets as 'use interrupt 6'.  This is likely the cause of much of
  the grief that we had when I enabled power modes for the cardbus
  bridge, since the card needed to reroute the interrupt to it and it
  was getting 6 which was d by the pccbb sanity checks.
