Some users prefer a single callback with length passed as parameter to using b/w/l callbacks. It would maybe be cleaner to just pass length to existing callbacks but that's a lot of churn. So for now add a wrapper. For convenience use pcibus_t for address so a single callback can be used for pci io and pci memory. I did have to resort to preprocessor to reduce code duplication. It is however slightly more straightforward, and better contained than what we had with pci_host_template.h. Again, it would go away if we just passed len to existing callbacks.
