After commit f1ad5338a4d5 ("of: Fix "dma-ranges" handling for bus
controllers"), the dma-ranges property is not allowed for
the leaf node. But our iommu/dma-ranges is 16GB, we still expect
separate the 16GB dma-range like:
a) display is in 0 - 4GB;
b) vcodec is in 4GB - 8GB;
c) camera is in 8GB - 12GB.
We can not expect all the masters add a parent node for them,
especial for the existed drivers/nodes.
Thus, we add whole the 16GB dma-ranges in the parent "soc" node.
