gpio: axp209: Implement get_direction
Implement the get_direction callback for the GPIOs found in the AXP209 PMIC. Due to the way they are implemented, in the same register you have the muxing options, GPIO directions and GPIO values. Since you have no control over what value is there at reset, simply use output as the default.
