gpio: mm-lantiq: 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: Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com> Cc: John Crispin <blogic@openwrt.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
