4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Viresh Kumar <viresh.kumar@linaro.org>
[ Upstream commit af0e09d0c6762e486b0eb5cc4737396964c34fad ]
The cooling device properties, like "#cooling-cells" and "dynamic-power-coefficient", should either be present for all the CPUs of a cluster or none. If these are present only for a subset of CPUs of a cluster then things will start falling apart as soon as the CPUs are brought online in a different order. For example, this will happen because the operating system looks for such properties in the CPU node it is trying to bring up, so that it can register a cooling device.
Add such missing properties.
