Power Station pin functions

Power Station Pin Function Mapping

To allow a single firmware to operate in different boards,
each board stores its pin function map in FRAM.
The map is 24 bytes, one for each of the 24 port pins.
Each byte contains the value of the function the respective pin performs.
