Master node corresponds to the device node, right? Master ID would correspond

to its corresponding IOMMU. We can use the same property instead of using "iommus".

I don't see "iommu-parent" used anywhere, just "fsl,iommu-parent". We can
probably allow "fsl,iommu-parent" as an alias for "iommus" for backwards-
compatibility if that helps you on PowerPC. For ARM, I'd prefer to mandate
that we use just "iommus".
