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

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).
