gpio: 104-idio-16: 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(). Acked-by: William Breathitt Gray <vilhelm.gray@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
