Move call to mySetup into IODevice::begin().

Browse Source 
Ensure that HAL devices are created before use by moving the call to mySetup into IODevice::begin().  The need for this became evident when it was noted that RMFT (EX-RAIL) interacts with HAL devices during its initialisation, by enabling pull-ups on digital inputs.
