[MIPS] Iomap implementation.
This implementation has support for the concept of one separate ioport address space by PCI domain. A pointer to the virtual address where the port space of a domain has been mapped has been added to struct pci_controller and systems should be fixed to fill in this value. For single domain systems this will be the same value as passed to set_io_port_base(). Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
