pci: Define pci_bus_dev_fn/pci_bus_fn/pci_bus_ret_fn

Browse Source 
They're used in quite a few places of pci.[ch] and also in the rest of the code
base.  Define them so that it doesn't need to be defined all over the places.

The pci_bus_fn is similar to pci_bus_dev_fn that only takes a PCIBus* and an
opaque.  The pci_bus_ret_fn is similar to pci_bus_fn but it allows to return a
void* pointer.
