pinctrl: bcm2835: 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: Stephen Warren <swarren@wwwdotorg.org> Acked-by: Eric Anholt <eric@anholt.net> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
