Dino Li 0174d4f85b it83xx: EC sleep mode for system hibernate
The typical power consumption in sleep mode is 65uA.

IT83xx uses deep doze mode for low power idle task. The typical power
consumption in this state is 280uA (depends on EC tasks, it should be more)
and the wake up time is in microsecond. We are using deep doze mode for
low power idle task instead of sleep mode is because the wake up time
will be 6ms more.

While in system hibernate (EC sleep mode), EC won't wake up frequently so
we can keep the power consumption at 65uA.
