arm64: dts: hisilicon: Add missing cooling device properties for CPUs
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. Do minor rearrangement as well to keep ordering consistent. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Wei Xu <xuwei5@hisilicon.com>
