The charger task was holding this either on or off in S3, no matter what we wanted. We really only need to set it at S3->S0 or S3->S5, or when the lid opens or closes. The rest of the time we should be able to turn it off and on with gpioset, for testing purposes. BUG=chrome-os-partner:26502 BRANCH=ToT TEST=manual Check the state with gpioget TOUCHSCREEN_RESET_L Open and close the lid, suspend the AP with powerd_dbus_suspend, etc. The touchscreen should be on when the lid is open and the AP is in either S3 or S0, off when the lid is closed or the AP is off. Then gpioset TOUCHSCREEN_RESET_L 1 gpioget TOUCHSCREEN_RESET_L gpioset TOUCHSCREEN_RESET_L 0 gpioget TOUCHSCREEN_RESET_L The change should persist as long as nothing else changes.
