gpiolib: add gpio get direction callback support Add .get_direction callback to gpio_chip. This allows gpiolib to check the current direction of a gpio. Used to show the correct gpio direction in sysfs and debug entries. If callback is not set then gpiolib will work as previously; e.g. guessing everything is input until a direction is set.
