You are correct that you should not merge a patch with the iommu reference before adding the iommu device node, because it would otherwise break building the mmc tree. One more point is the binding for IOMMU needs to be in the same patch in which the IOMMU support is added. So to provide the binding info of the master node we require the sdhc nodes to be merged first. Usually, the right answer is to merged the dts changes through the arm-soc tree, and then you can just add the node for the sdhc device after the one for the iommu device.
