UPSTREAM: mainboard/google/poppy: Enable deep S3 in DC mode

Browse source 
Enable lower power state when running on battery. Deep S3 is not
enabled when in AC mode to support standard "docked" config.

BUG=b:36087058,b:36723679
TEST=Verified following behavior with USB mouse:
1. If AC is connected when entering S3, USB mouse is able to wake up.
2. If AC is not connected when entering S3, USB mouse does not wake up.
3. If AC is connected when entering S3 and removed after entering S3,
USB mouse does not wake up.
4. If AC is not connected when entering S3 and attached after entering
S3, USB mouse does not wake up.
