4.4-stable review patch. If anyone has any objections, please let me know.

commit acbf76ee05067c3942852019993f7beb69a0f45f upstream.
dtc complains about the lack of #coolin-cells properties for the CPU nodes that are referred to as "cooling-device":
arch/arm64/boot/dts/mediatek/mt8173-evb.dtb: Warning (cooling_device_property): Missing property '#cooling-cells' in node /cpus/cpu@0 or bad phandle (referred from /thermal-zones/cpu_thermal/cooling-maps/map@0:cooling-device[0]) arch/arm64/boot/dts/mediatek/mt8173-evb.dtb: Warning (cooling_device_property): Missing property '#cooling-cells' in node /cpus/cpu@100 or bad phandle (referred from /thermal-zones/cpu_thermal/cooling-maps/map@1:cooling-device[0])
Apparently this property must be '<2>' to match the binding.
