board/fleex/gpio: Add missing GPIO configuration for Board Id 2
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. Update the name
for CCD_MODE_EC_L pin. Add configuration for USB_C_OC and
TRACKPAD_INT_1V8_ODL pins.
BRANCH=None
BUG=b:110192175
TEST=make -j buildall && Bootup to chromeos. Also verified that power
stayed the same or slightly lower(18.67mW on PP3300_ec_mw to 18.23 mW over
10 sec average on Grabitter).
