mips: use the the PCI controller's io_map_base
commit eab90291d35438bcebf7c3dc85be66d0f24e3002 (mips: switch to GENERIC_PCI_IOMAP) failed to take into account the PCI controller's io_map_base for mapping IO BARs. This also caused a new warning on mips. Fix this, without re-introducing code duplication, by setting NO_GENERIC_PCI_IOPORT_MAP and supplying a mips-specific __pci_ioport_map.

Find out whether you have a PCI motherboard. PCI is the name of a
bus system, i.e. the way the CPU talks to the other stuff inside
