px4fmu-v5:Define ADC GPIO and Channels clearly

Browse Source 
Moving forward we want all the board configs to drive the
   configuration. This is just cleanup to give a clear
   example of how ADC should be defined by a simple list,
   based on ADC pin number as related to the GPIO and
   channel number. Then the xxx_CHANNEL bit are
   used to form the ADC_CHANNELS (mask). The GPIO
   will are used to for a list for initalization.
