pinctrl/samsung: don't allow enabling pinctrl-samsung standalone
The main samsung pinctrl module references the specific exynos4210
pinctrl driver, which selects the main driver in Kconfig.
Making the main driver a silent "bool" option avoid this potential
build error if CONFIG_PINCTRL_SAMSUNG=y && CONFIG_PINCTRL_EXYNOS4=n:
drivers/built-in.o:(.rodata+0x4e4): undefined reference to `exynos4210_pin_ctrl'
