Actually we were only adding cooling-cells in CPU0 until now and I
fixed that, so that is going to stay :)

The idea is that the hardware should be described properly and not
partially. Even if all the CPUs are part of the same freq-domain, they
are all capable of being a cooling device here and the DT should
describe that. Kernel will ofcourse create a single cooling device.
