In order to support dynamic frequency scaling: * the cpuclk Device Tree node needs to be updated to describe a second set of registers describing the PMU DFS registers. * the clock-latency property of the CPUs must be filled, otherwise the ondemand and conservative cpufreq governors refuse to work. The latency is high because the cost of a frequency transition is quite high on those CPUs.
