Any requirement of FWU should not require changes to bindings of other subsystems. For example, for mtd-backed storage we can do without requiring 'fixed-partitions' children to also carry 'uuid', a property which is non-standard and not in the bindings. There exists no code yet, so we can change the fwu-mtd bindings to contain all properties within the fwu-mdata node.
