Instead of introducing pci_next_in_bus(), can't we just use the
existing pci_next() call?  Something like:

#define foreachpci_in_bus(BDF, MAX, BUS)              \
    for (MAX=(BUS + 0x0100), BDF = BUS                \
         ; BDF >= 0 && BDF < (BUS + 0x0100)           \
         ; BDF = pci_next(BDF+1, &MAX))
