mb/google/zork/var/ezkinil: Fix stylus GPIO to enable suspend 

Make GPIO_4 and GPIO_5 PAD_NC in ezkinil/gpio.c. None of the Ezkinil SKUs
use internal stylus and hence pen pads are configured as NC.

BUG=b:164892883, b:165342107
TEST=Verified taht pen detect GPIO does not cause spurious wakes.
BRANCH=None
