On the Lenovo X13s attaching to the multiport USB controller leads to hard
resets.  Previously this was only seen with smmu(4) enabled, probably as
there is no IORT reference to that controller and hence no IOMMU mapping
established.  Since recent BIOS updates, this now also happens without
smmu(4) enabled.  Let's skip this node for now to keep machines running.
