- The IQ80321 has a jumper which changes the PCI device id from 4 to 8 for the

GigE controller, so handle this.
- Use the outbound window 0 if the PCI mem requested is in its range, instead
of inconditionally use the outbound window 1.
This should be enough to get FreeBSD/arm to work on the IQ80321 board as well.
