[PATCH] pinctrl: samsung: Fix missing OF and GPIOLIB dependency on S3C24xx and S3C64xx

[Krzysztof Kozlowski]

All Samsung pinctrl drivers select common part - PINCTRL_SAMSUNG which uses
both OF and GPIOLIB inside.  However only Exynos drivers depend on these,
therefore after enabling COMPILE_TEST, on x86_64 build of S3C64xx driver
failed:

    drivers/pinctrl/samsung/pinctrl-samsung.c: In function âsamsung_gpiolib_registerâ:
    drivers/pinctrl/samsung/pinctrl-samsung.c:969:5: error: âstruct gpio_chipâ has no member named âof_nodeâ
       gc->of_node = bank->of_node;
         ^

Rework the dependencies so all Samsung drivers and common
PINCTRL_SAMSUNG part depend on OF_GPIO (which is default yes if GPIOLIB
and OF are enabled).
