Why do you want to use the "Port Bus Driver Model"? That is only intended for the ports in PCIe switches. Does your card include a switch with non-standard services? If your driver is specifically for some new switch functionality, you might want to make it a port service driver. But if this is a PCIe endpoint device, then you should make it a plain old PCI driver with pci_register_driver().
