By default MIPS architecture use function 'set_io_port_base()' to set the virtual address of the first IO port. This function at the end sets variable 'mips_io_port_base' with the desired address. To align things and allow to change first IO port location address for PCI, set PCI_IOBASE definition as 'mips_io_port_base'. Also, we only need a size of 64 KB.
