cpufreq: Clarify the comment in cpufreq_set_policy()
One of the responsibility of the ->verify() callback is to make sure that the policy's min frequency is <= max frequency as this isn't guaranteed by the QoS framework which gave us those values. Update the comment in cpufreq_set_policy() to clarify that. Suggested-by: Rafael J.
