This patch enables the CPU frequency scaling for exynos3250-artik5 module
and adds the thernal zones with cpu cooling device to prevent the overheat
temperature.

The patch looks good but just squash it with 5/10 unless there is some
benefit by splitting the features for many patches. The benefit would be
for example submitting the work partially, in steps, following principle
release-early-release-often... but this is not the case. You have
everything ready and tested.

BR,
Krzysztof

OK. I'll merge this patch with 5/10 patch.
