Although the driver has some support implemented for non-PCI devices via ANDD, it only registers itself for pci_bus_type, so has never actually seen probe_device for a non-PCI device. Once the bus details move into the IOMMU core, it appears there may be some issues with correctly rejecting non-ANDD platform devices, so let's temporarily enforce the current behaviour of only considering PCI devices until that can be investigated properly.
