It seems that we need to map the CPUs in the cpus node to the frequency
domains in the cpufreq-hw node. Wouldn't that be better served via a
#foo-cells and <&phandle foo-cell> property in the CPU node? It's
annoying that the cpufreq-hw node doesn't have a reg property, when it
really should have one that goes over the whole register space (or is
split across the frequency domains so that there are two reg properties
here).
