ARM: Kirkwood add cpus definition needed by cpufreq driver to dtsi
The Kirkwood CPU Freq driver needs a CPU definition in order for the probe routine to activate it. Add a suitable definition to kirkwood.dtsi This definition is only correct for single core SoCs. There is a dual core SoC in the kirkwood family (88F632X) but the rest of the Kirkwood drivers in the kernel don't currently support it. If they ever do the cpus definition would need to be duplicated in each of the SoC specific include files.
