board/bobba/gpio: Add missing GPIO configuration for Board Id 3
Set the unused pins as input with an internal pull-up. This helps save
some power. Update the name for the CCD_MODE_EC_L pin. Add configuration
for USB_C_OC & 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(5.28mW on PP3300_ec_mw to 5.27 mW over
10 sec average on Bobba360).
