Now that I see the current implementation, I think we can make it work
in a different way.

- Copy what's done for thermal-cooling in cpufreq core, i.e.
  CPUFREQ_IS_COOLING_DEV flag, for the EM core as well. So the cpufreq
  drivers can set a flag, CPUFREQ_REGISTER_EM, and the cpufreq core
  can call dev_pm_opp_of_register_em() on their behalf. This call will
  be made from cpufreq_online(), just before/after
  cpufreq_thermal_control_enabled() stuff. By this point the policy is
  properly initialized and is also updated in
  per_cpu(cpufreq_cpu_data).

And I was able to get something out for this:
