PM / OPP: Rename OPP nodes as opp@<opp-hz>
It would be better to name OPP nodes as opp@<opp-hz> as that will ensure that multiple DT nodes don't contain the same frequency. Of course we expect the writer to name the node with its opp-hz frequency and not any other frequency. And that will let the compile error out if multiple nodes are using the same opp-hz frequency.
