Subject: [PATCH] zephyr-openthread-rcp: refuse to build with ACM0 console
enabled
The OpenThread border router on linux uses the USB console on the
antenna running zephyr. The ACM0 patch gets in the way and disables the
OpenThread interface. Error out if the user tries to have this option
enabled and build the antenna firmware.
