board/meep/gpio: Add missing GPIO configuration for Board Id 1
Set the unused pins as input with an internal pull-up if there is no external pull-up/pull-down. This helps save some power. BRANCH=None BUG=b:110192175 TEST=make -j buildall && Bootup to chromeos. Also verified that power stayed the same or slightly lower(5.51mW on PP3300_ec_mw to 5.51 mW over 10 sec average on Meep).
