pinctrl: Use new GPIO_LINE_DIRECTION Use newly added GPIO defines GPIO_LINE_DIRECTION_IN and GPIO_LINE_DIRECTION_OUT instead of using hard-coded 1 and 0. Main benefit is to make it easier to see which values mean IN and which OUT. As a side effect this helps GPIO framework to change the direction defines to something else if ever needed. Please note that return value from get_direction call on pinctrl-axp209 driver was changed. Previously pinctrl-axp209 might have returned value 2 for direction INPUT.
