nrf/boards/make-pins.py: Fix gen of board pins to use correct index.

Browse Source 
It was previously not taking into account that the list of pins was sparse,
so using the wrong index.  The boards/X/pins.csv was generating the wrong
data for machine.Pin.board.

As part of this fix rename the variables to make it more clear what the
list contains (only board pins).
