hciuart service fails

[xmacex]

A very minor thing, but the hciuart systemd service is always failing. Upon inspection

norns has no BlueTooth modems connected by UART, and as I understand BlueTooth is disabled in the kernel. I might be wrong, and it's used in development or the wifi dongle on factory norns or something (I have a shield).

I suggest considering disabling this service in the norns image so it won't be there to fail -- it's tragic life is lived in hopeless disappointment. systemctl hciuart disable.
