thermal: cooling: Check Energy Model type in cpufreq_cooling and devfreq_cooling

The Energy Model can now be artificial, which means the power values
are mathematically generated to leverage EAS while not expected to be on
an uniform scale with other devices providing power information. If this
EM type is in use, the thermal governor IPA should not be allowed to
operate, since the relation between cooling devices is not properly
defined. Thus, it might be possible that big GPU has lower power values
than a Little CPU. To mitigate a misbehaviour of the thermal control
algorithm, simply do not register the cooling device as IPA's power
actor.
