Subject: [PATCH] power: energy_model: Rework the depends on for CONFIG_ENERGY_MODEL

From: Jeson Gao <jeson.gao@...soc.com>

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.
