Steve Muckle a2c6c91f98 sched/fair: Call cpufreq hook in additional paths ...

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().

Suggested-by: Vincent Guittot <vincent.guittot@linaro.org>
Signed-off-by: Steve Muckle <smuckle@linaro.org>
[ Added the .update_freq argument to update_cfs_rq_load_avg() to avoid a double cpufreq call. ]
