gpio: f7188: 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: Andreas Bofjall <andreas@gazonk.org> Cc: Simon Guinot <simon.guinot@sequanux.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
