The cpufreq hook should be called any time the root CFS rq utilization changes. This can occur when a task is switched to or from the fair class, or a task moves between groups or CPUs, but these paths currently do not call the cpufreq hook. Fix this by adding the hook to attach_entity_load_avg() and detach_entity_load_avg().
