Warn on node name unit-address presence/absence mismatch ePAPR 1.1 section 2.2.1.1 "Node Name Requirements" specifies that any node that has a reg property must include a unit address in its name with value matching the first entry in its reg property. Conversely, if a node does not have a reg property, the node name must not include a unit address. Also allow ranges property as it is deemed valid, but ePAPR is not clear about it. Implement a check for this. The code doesn't validate the format of the unit address; ePAPR implies this may vary from (containing bus) binding to binding, so doing so would be much more complex.
