EC: Implementation for AP reboot from G3 state using ectool command.
The new ectool command 'ectool reboot_ap_on_g3' will reboot AP from
G3 state on initiation of DUT shutdown. Thus eliminating the dependency
of servo to trigger wake events when testing AP cold boot cycles.
BUG=b:129507479
BRANCH=None
TEST=Tested on hatch board.
From Kernel console, entered the below commands:
$ectool reboot_ap_on_g3
$shutdown -h now
Observed AP boots back to S0 upon G3.
