    PCI: Convert pcibios_resource_to_bus() to take a pci_bus, not a pci_dev · fc279850

    These interfaces:
    
      pcibios_resource_to_bus(struct pci_dev *dev, *bus_region, *resource)
      pcibios_bus_to_resource(struct pci_dev *dev, *resource, *bus_region)
    
    took a pci_dev, but they really depend only on the pci_bus.  And we want to
    use them in resource allocation paths where we have the bus but not a
    device, so this patch converts them to take the pci_bus instead of the
    pci_dev:
    
      pcibios_resource_to_bus(struct pci_bus *bus, *bus_region, *resource)
      pcibios_bus_to_resource(struct pci_bus *bus, *resource, *bus_region)
    
    In fact, with standard PCI-PCI bridges, they only depend on the host
    bridge, because that's the only place address translation occurs, but
    we aren't going that far yet.
