Not sure which code you are looking at, but as I see it we have only per-device iommu-ops now (with this patch). That is different from having core-visible hardware-iommu instances where devices could link to. Also the rest of iommu-core code still makes use of the per-bus ops. The per-device ops are only used for the of_xlate fn-ptr.
