mb/google/sarien: Force power on after cr50 update
By default this board is configured to not power up after an EC reset. However in the case of a cr50 firmware update that will reset the EC it will end up powered off. In order to have it stay powered up configure the board to power up. This will get reset to the configured default when it boots again. BUG=b:121380403 TEST=update cr50 firmware and reboot to ensure system boots and does not end up powered off.
