npcx: Move pwm open-drain functionality from gpio to pwm driver.
Setting PWM IO type in gpio driver seems not a proper way. This
CL moves this functionality to pwm driver and introduces a new
flag PWM_CONFIG_OPEN_DRAIN to achieve it when user declared it
in board driver.
BRANCH=none
BUG=none
TEST=test pwm functionality on npcx_evb.
