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 at 0 or bad phandle (referred from /thermal-zones/cpu_thermal/cooling-maps/map at 0:cooling-device[0])
arch/arm64/boot/dts/mediatek/mt8173-evb.dtb: Warning (cooling_device_property): Missing property '#cooling-cells' in node /cpus/cpu at 100 or bad phandle (referred from /thermal-zones/cpu_thermal/cooling-maps/map at 1:cooling-device[0])

Apparently this property must be '<2>' to match the binding.

If this looks ok, I'd apply it directly to the fixes branch
for 4.15, as the warning is one that was introduced in this
release.

Actually, it's in next/dt (or at least this patch doesn't apply as it is to
fixes), so I've added it there.
