pci: Add pci_dev_bus_num() helper
A fair proportion of the users of pci_bus_num() want to get the bus number on a specific device, so first have to look up the bus from the device then call it. This adds a helper to do that (since we're going to make looking up the bus slightly more verbose). Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Reviewed-by: Michael S.
