PM / devfreq: tegra30: Support thermal cooling
Expose ACTMON devfreq device as a cooling device in order to throttle memory freq on overheat. Throttling of memory freq has a significant cooling effect on NVIDIA Tegra SoCs since higher memory freqs require higher SoC core voltage which is one of the main causes of the heating.
