I do not think DVFS layer can be made a generic layer outside OMAP because
of the fact that DVFS is closely coupled with OMAP device layer (for
getting hwmod related data and clock handling), OMAP voltage layer (for
voltage scaling and handling of dependency voltage domains) and smart
reflex layer.
