This patch fixes below build error when !CONFIG_OF_GPIO.
CC drivers/pinctrl/pinctrl-samsung.o
drivers/pinctrl/pinctrl-samsung.c: In function 'samsung_pinctrl_parse_dt_pins':
drivers/pinctrl/pinctrl-samsung.c:557:19: warning: unused variable 'prop'

drivers/pinctrl/pinctrl-samsung.c: In function 'samsung_gpiolib_register':

make: *** [drivers] Error 2
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.

Hi Thomas,
If I simply add "select OF_GPIO" for PINCTRL_SAMSUNG, I got below build warning:
warning: (PINCTRL_SAMSUNG) selects OF_GPIO which has unmet direct dependencies
(GPIOLIB && OF && !SPARC)
So I make PINCTRL_SAMSUNG depend on OF && GPIOLIB.
Regards,
Axel
