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.

pinctrl: samsung: Fix missing OF and GPIOLIB dependency on S3C24xx and S3C64xx

All Samsung pinctrl drivers select common part - PINCTRL_SAMSUNG which uses
both OF and GPIOLIB inside. However only Exynos drivers depend on these,
therefore after enabling COMPILE_TEST, on x86_64 build of S3C64xx driver
failed:

drivers/pinctrl/samsung/pinctrl-samsung.c: In function ‘samsung_gpiolib_register’:
drivers/pinctrl/samsung/pinctrl-samsung.c:969:5: error: ‘struct gpio_chip’ has no member named ‘of_node’
gc->of_node = bank->of_node;
^

Rework the dependencies so all Samsung drivers and common
PINCTRL_SAMSUNG part depend on OF_GPIO (which is default yes if GPIOLIB
and OF are enabled).

pinctrl: samsung: Split Exynos drivers per ARMv7 and ARMv8

Exynos pinctrl drivers contain pretty big per-SoC data structures. The
pinctrl-exynos object file contained code and data for both ARMv7 and
ARMv8 SoCs thus it grew big. There will not be a shared image between
ARMv7 and ARMv8 so there is no need to combine all of this into one
driver.

Splitting the data allows to make it more granular (e.g. code related to
ARMv8 Exynos is self-contained), slightly speed up the compilation and
reduce the effective size of compiled kernel.

The common data structures and functions reside still in existing
pinctrl-exynos.c. Only the SoC-specific parts were moved out to new
files. Except marking few functions non-static and adding them to
header, there were no functional changes in the code.
