As I think this should not all be handled by GPIO, the joystick on
gpio-keys needs a pin control handle pointing back to pin control
states on the respective pins in the pin control/GPIO driver,
where it can set up these properties.
For the individual lines the pushing and pulling flags should be
removed.
