ARM: mvebu: update Armada XP DT for dynamic frequency scaling
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.
