Liang Chen 51d4aae73f sched/fair: optimize scheduler for performance ...

1. init util_avg of new task to half the util of big core.
2. treat task wait time as busy time.
3. do not put task to the cpu whose max util can not fit the task.
4. boost cpufreq when a task is wakeup.

if prefer powersave, we can disable this optimization by command:

echo 0 > /proc/sys/kernel/sched_performance_bias
