Implement BUSDMA_IOMMU_MAP. We want to map starting with the root and
ending with the leaf. In other words, we want to map top-down (root to
leaf) and not bottom-up (learfd to root).  Given that we have a fairly
shallow device tree, use recursion to walk up to the root first and
then call the BUSDMA_IOMMU_MAP on the device on the way back down (i.e.
while unwinding from the recursion.  At the root, bus addresses are
the same as CPU (physical addresses), so we assign the CPU address to
the bus address.
