PM: EM: Rework the depends on for CONFIG_ENERGY_MODEL

Browse source 
Now not only CPUs can use energy efficiency models, but GPUs
can also use. On the other hand, even with only one CPU, we can also
use energy_model to align control in thermal.
So remove the dependence of SMP, and add the DEVFREQ.
