Intention of chipset_force_shutdown is to power off the AP by simulating power button press until it results in power button override and shuts down AP. However, if AP is already in hard or soft off conditions (i.e. G3, S5G3, G3S5 or S5) then AP is already off, and simulating power button press results in charge_prevent_power_on from incorrectly assuming that the power button is pressed by user. Thus, check if the system is in soft or hard off before shutting it down. BUG=b:65864825 BRANCH=None TEST=Verified that apshutdown still works fine from EC console on soraka.
