stm32: don't try to use the AP I2C connection when the CPU is running
If the EC shares the I2C-2 bus with the battery and the charger, we
don't want to be a master on that bus when the AP is ON and can send us
I2C messages.
Signed-off-by: Vincent Palatin <vpalatin@chromium.org>
BUG=none
TEST=on Lucas DVT, check we can read battery info when AP is OFF and we
cannot when AP is ON.
