Otherwise we only look for one device below a PCIe downstream port.
The "pci=noats" kernel parameter disables PCIe ATS globally, and affects any ATS-capable IOMMU driver. So rather than adding Arm SMMUv3, which recently gained ATS support, to the list of relevant build options, simplify the noats description.
