The ti,j721e-ufs schema and example have a couple of problems related to address properties. First, the default #size-cells and #address-cells are 1 for examples, so they need to be overriden with a bus node. Second, address translation for the child ufs node is broken because 'ranges', '#address-cells', and '#size-cells' are missing from the schema.
