Use single ring buffer and protect it with a spinlock as it is shared between backend and UART thread (ISR). This is simpler than the double ring buffer setup. The receive idle timeout has also been made configurable instead of being a hardcoded value. Signed-off-by: Bjarki Arge Andreasen <bjarki@arge-andreasen.me>
