Change some light idle alarms to non-wakeup.

Changing some light idle alarms to non-wakeup to reduce the number of
alarms that could potentially wake up the device. If the CPU is already
in suspend, we don't need to wake it up just to officially enter doze
light. We can just wait until the CPU wakes up to do the transition. On
a particularly active device, this won't change the time we enter Doze
light much, but on a quiet device, the Doze light and maintenance
windows may be shifted significantly.
