Move toggling of kernel idle timer to SF
Idle timer is toggled from the SF code using the following logic:
- If the device policy refresh rate min = max, we turn off the timer.
- If the device policy refresh rate min > the device min,
we turn off the timer.
- Do not toggle the timer if deviceMin == policyMin.
- Timer is on in all other cases.
