The cpufreq driver uses the PMU node in the device tree, since it is
part of the PMU device. The dove-cpufreq driver needs access to the
DDR and CPU clock, which are the two clocks the CPU can use. There is
also an interrupt generated when the DFS hardware completes a change
of frequencey. Add these to the DT.
