Leaning the code-Threading : Timer callback function's formal parameter need to be change.

[dammstanger]

In the timer callbacks,register a timer callback function's formal parameter:
AP_HAL_MEMBERPROC(&AP_Baro_MS5611::_update)
need to be change into:
FUNCTOR_BIND_MEMBER(&AP_Baro_MS5611::_update, void) or
FUNCTOR_BIND(<instance>, &AP_Baro_MS5611::_update, void) for specific instance.
