ARM: shmobile: sh73a0: add CPUFreq support
This patch enables the use of the generic cpufreq-cpu0 driver on sh73a0. Providing a regulator, a list of OPPs in DT, combined with a virtual cpufreq-cpu0 platform device and a clock, attached to it is everything, the cpufreq-cpu0 driver needs. The first sh73a0 platform, implementing such CPUFreq support is kzm9g-reference.
