case (ne@pcmcia) where we were using these to create a subregion, it is better handled by calling bus_space_subregion(). Now there is a 1:1 mapping between I/O spaces in the config table and windows mapped in the function. Rework the multifunction mapping code to take advantage of this by using both I/O base addresses if necessary.
