ssb: gpio_driver: 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: Hauke Mehrtens <hauke@hauke-m.de> Cc: Michael Buesch <m@bues.ch> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
