commit ac875df4d854ab13d9c4af682a1837a1214fecec upstream.

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.
