Add an offset to the I/O port translations. This allows IQ80321
and others to avoid providing PCI I/O space at address 0.
Iyonix, however, needs to provide PCI I/O space at 0.
The others require I/O space to be offset in part due to a bug
work-around in wm(4) which requires that I/O space access be used
to reset the controllers. If I/O space is mapped at zero, the card
claims, but ignores, the transactions, and the controller doesn't
get reset properly and can't then be used.
