mips: switch to GENERIC_PCI_IOMAP

mips copied pci_iomap from generic code, probably to avoid
pulling the rest of iomap.c in.  Since that's in
a separate file now, we can reuse the common implementation.

          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
