pinctrl: spmi: 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: Ivan T. Ivanov <ivan.ivanov@linaro.org> Cc: Björn Andersson <bjorn.andersson@sonymobile.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
