driver: gpio: npcx: force io type as open-drain if select to 1p8v.
During configuring the low-voltage power supply of IO pads, the npcx
GPIO driver needs to set the related PORTx_OUT_TYPE bit to 1, i.e.
select to 'Open Drain IO type', also. This CL provides a mechanism that
configuring these bits via 'def-lvol-io-list' node automatically in case
the flag of gpios that have been configured to low-voltage power supply
doesn't contain GPIO_OPEN_DRAIN.
