MIPS: txx9: iocled: 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: linux-mips@linux-mips.org Acked-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
