PCI: Add pci_ops.{add,remove}_bus() callbacks
Add pci_ops.{add,remove}_bus() callbacks, which will be called on every newly created bus and when a bus is being removed, respectively. This can be used by drivers to implement driver-specific initialization and teardown of the bus, in addition to the architecture-specifics implemented by the pcibios_add_bus() and the pcibios_remove_bus() functions.
