vortex86ex: Change PCI S/B resource reservation functions for more I/O devices. 

Originally, Vortex86EX PCI S/B internal resource reservation functions can
only support one big legacy I/O device space (0-0xfff).

Change function signature to support other non-legacy I/O device space in
the future.
