Flapjack: Cut off battery when USB-C board isn't connected
Currently, when a battery is connected, the device boots immediately.
This makes assembly process unreliable.
This patch makes EC cut off a battery at start-up if USBC_THERM reads
about the pull-up voltage because that indicates a USB-C board isn't
connected, which means the devices is being assembled.
