Remove some of the 'onion'. This simplifies also the coming usage of the gpiolib defines. We can do conversion from chip bits to gpiolib direction defines as last step in the get_direction callback. Drivers can use chip specific values in driver internal functions and do conversion only once.

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.
