Ah, good point. My inclination would be to, rather than check how we
got to the node, check whether it's the device's parent. If not, then
the presence of #address-cells (other than zero for compatibility) is an
error. Otherwise, #address-cells is used, and defaults are handled the
same as with reg/ranges translation.
