This bug is to track system S4 suspend performance issue. The requirement defines that "Time from user pressing sleep button to platform going to S4 state (not just display going blank) <= 10 sec", right now we need 21sec even if system is idle with nothing played.

Reproduce steps:
----------------
1. ume-hibernate to S4 suspend the system, and record the time

Current result:
----------------
The S4 hibernate suspend time is longer than required

Expected result:
----------------
1. S4 hibernate suspend time should be less than 10s per defined.

Basic root-causing log:
