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).
