to child if an auxillary PCI bus is attached to the bridge.  Also,
remove an extra ';'.

a492e1df80 Add a kernel driver for the APCI 8250-like UARTs that live in the 
Frodo ASIC, originally contributed by Mike Smith
<mike@pressed.spam.frisbee.net.au>, but reworked by me to:
- Essentially duplicate the dca driver, modifiying where necessary
  to work with the APCI.
- Deal with the different Frodo autoconfiguration model.
- Don't attach a tty to the 0th UART - it's not really useful for much
  more than the Domain keyboard.
- Added a routine to check for the existence of a DCA at select code 9.
  On most models, the 1'th UART is mapped to select code 9 by the PROM,
  and on these models, we do _NOT_ want to attach the device as an APCI.
  However, on the 425e, this mapping does not take place, so we attach
  as an APCI.  The 2'th and 3'th UARTs always get tty instances.
- Add console support which will only be invoked on the 425e (i.e. check
  for DCA at 9, and defer console to it if it exists).
