ARM: w90x900: 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: arm@kernel.org Acked-by: Olof Johansson <olof@lixom.net> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
