pci: Add pci_dev_bus_num() helper

Browse source 
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).
