It already does that... or at least it should. in cpufreq_resume() there is
a call to schedule_work(&cpu_policy->update); which will cause a call
cpufreq_update_policy() in due course. And cpufreq_update_policy() calls the
governor, and it is supposed to adjust the frequency to the user's wish
then.
