Subject: [PATCH] pinctrl: samsung: fix missing GPIOLIB on ARM64 Exynos config

The Samsung pinctrl drivers depend on OF_GPIO, which is part of GPIOLIB. ARMv7 Exynos platform selects GPIOLIB and Samsung pinctrl drivers. ARMv8 Exynos selects only the latter leading to possible wrong configuration on ARMv8 build:

WARNING: unmet direct dependencies detected for PINCTRL_EXYNOS
Depends on [n]: PINCTRL [=y] && OF_GPIO [=n] && (ARCH_EXYNOS [=y] || ARCH_S5PV210 || COMPILE_TEST [=y]) Selected by [y]:
- ARCH_EXYNOS [=y]

Always select the GPIOLIB from the Samsung pinctrl drivers to fix the issue. This requires removing of OF_GPIO dependency (to avoid recursive dependency), so add dependency on OF for COMPILE_TEST cases.
