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.
