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.
