PCI: add generic device into pci_host_bridge struct
Use that device for pci_root_bus bridge pointer.
Use pci_release_bus_bridge_dev() to release allocated pci_host_bridge in
remove path.
Use root bus bridge pointer to get host bridge pointer instead of searching
host bridge list. That leaves the host bridge list unused, so remove it.
