gpio: ml-ioh: use gpiochip data pointer
This makes the driver use the data pointer added to the gpio_chip to store a pointer to the state container instead of relying on container_of(). Cc: Feng Tang <feng.tang@intel.com> Cc: Tomoya MORINAGA <tomoya-linux@dsn.okisemi.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
