Sorry for not picking this earlier, but you should probably add the same clock
related properties for both cpu nodes here. Things will break if CPU1 is used by
the cpufreq core to bring the cpufreq policy online.

This can happen if cpufreq driver is a module, CPU0 is hotplugged out and then
the cpufreq driver is inserted.
