spring: Fix S3 USB charging bug

Browse Source 
The EC currently assumes the AP only provides USB power during S0, which
is incorrect. This CL adds S3 so that it behaves when the device is
suspended.

BUG=chrome-os-partner:19190
TEST=Suspend and unplug power. Doesn't hear clicking sound.
BRANCH=Spring
