[PATCH -next] pinctrl: samsung: fix build error without CONFIG_OF_GPIO

[Chen Zhou]

If CONFIG_OF_GPIO is n, build fails:

drivers/pinctrl/samsung/pinctrl-samsung.c: In function samsung_gpiolib_register:
drivers/pinctrl/samsung/pinctrl-samsung.c:969:5: error: struct gpio_chip has no member named of_node
   gc->of_node = bank->of_node;

Use #ifdef to guard this.
