[V2,4/5] PM / OPP: Rename OPP nodes as opp@<opp-hz>

Message ID 5d5f139d334d5e503932c06694b47f0c3477caed.1446687367.git.viresh.kumar@linaro.org

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.
