Having static inline oneliner does not benefit too much when it is only called from another oneliner function. 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.
