    [POWERPC] Fix pci_setup_phb_io_dynamic for pci_iomap
    We had a problem on a system with only dynamically allocated
    PCI buses (using of_pci_phb_driver) in combination with libata.
    This setup ended up having no "primary" phb, which means
    that pci_io_base never got initialized and all IO port
    numbers are 64 bit numbers, which is larger than the
    PIO_MASK limit.
