For MIPS PCI, use the resources-list style to set up root resources rather than
filling in pci_bus->resource[] array directly. This will hide some ugly
implementation details.

In addition, change the pci_create_bus() interface to pass in available
resources to get them settled down early. This is to avoid possible resource
conflicts while doing pci_scan_slot() in pci_scan_child_bus(). Note that
pcibios_fixup_bus() can get rid of such conflicts, but it's done AFTER scanning
slots.

Deng-Cheng Zhu (3):
  MIPS: PCI: Use pci_bus_remove_resources()/pci_bus_add_resource() to
    set up root resources
  PCI: Pass available resources into pci_create_bus()
  MIPS: PCI: Pass controller's resources to pci_create_bus() in
    pcibios_scanbus()
