clk: samsung: add CONFIG_OF dependency

When CONFIG_OF is disabled, build testing on x86 runs into a couple of
objtool warnings from functions that unconditionally call panic() but
have no __noreturn annotation:

vmlinux.o: warning: objtool: exynos3250_cmu_isp_probe+0x17: samsung_cmu_register_one() is missing a __noreturn annotation
vmlinux.o: warning: objtool: exynos7885_cmu_probe+0x16: exynos_arm64_register_cmu() is missing a __noreturn annotation
vmlinux.o: warning: objtool: exynos850_cmu_probe+0x16: exynos_arm64_register_cmu() is missing a __noreturn annotation
vmlinux.o: warning: objtool: exynosautov9_cmu_probe+0x16: exynos_arm64_register_cmu() is missing a __noreturn annotation

The objtool analysis is correct, and this could be addressed by just
returning success whenever CONFIG_OF is disabled to let all that code
be eliminated, but since the driver is no use without CONFIG_OF,
just add that as a dependency. It will still get compile tested on
all architectures since CONFIG_OF is enabled in allmodconfig and most
randconfig builds.

clk: samsung: Allow compile testing of Exynos, S3C64xx and S5Pv210

So far all Exynos, S3C64xx and S5Pv210 clock units were selected by
respective SOC/ARCH Kconfig option. On a kernel built for selected
SoCs, this allowed to build only limited set of matching clock drivers.
However compile testing was not possible in such case as Makefile object
depends on SOC/ARCH option.

Add separate Kconfig options for each of them to be able to compile
test.

There won't be a single kernel image for ARMv7 and ARMv8 SoCs (like
multi_v7 for ARMv7).

Instead build clock drivers only for respective SoC's architecture.
