When we don't have any file in cpu/cpufreq directory we shouldn't create it. Specially with the introduction of per-policy governor instance patchset, even governors are moved to cpu/cpu*/cpufreq/governor-name directory and so this directory is just not required.
Lets have it only when required.

Global symbol names should begin with a sensible prefix; in this case, it looks like cpufreq_get_global_kobject and cpufreq_put_global_kobject would be more appropriate names.
