PWT buzzer driver: conditionalize on TARGET_HAS_BUZZER Here we add a new target config preprocessor symbol TARGET_HAS_BUZZER, currently defined for c11x and c139; later we also expect to have it on for FC Venus, and in FC Magnetite we are going to turn it on for target dsample, just for the sake of completeness and philosophical correctness.
