PCI: replace struct pci_bus secondary/subordinate with busn_res
Replace the struct pci_bus secondary/subordinate members with the struct resource busn_res. Later we'll build a resource tree of these bus numbers. [bhelgaas: changelog] Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
