sched: add hmp boost for big-little cluster [1/1]

PD#SWPL-6980

Problem:
memory bound tasks running in a high freq cluster will get a low performance
when another cluster freq is too low.

Solution:
We boost big cluster freq for a appropriate duration when we detect that
little cluster have lasting a period with highest freq.

Verify:
