pinctrl: samsung and exynos need to depend on OF && GPIOLIB

This patch fixes below build error when !CONFIG_OF_GPIO.

  CC      drivers/pinctrl/pinctrl-samsung.o

The samsung pinctrl driver supports only device tree enabled
platforms. Thus make PINCTRL_SAMSUNG depend on OF && GPIOLIB.

The reason to depend on GPIOLIB is CONFIG_OF_GPIO only available
when GPIOLIB is selected.

Since PINCTRL_EXYNOS4 select PINCTRL_SAMSUNG, thus also make
PINCTRL_EXYNOS4 depend on OF && GPIOLIB.
