Subject: [PATCH v4 2/3] clk: samsung: Don't build ARMv8 clock drivers on ARMv7
Currently the Exynos5433 (ARMv8 SoC) clock driver depends on ARCH_EXYNOS
so it is built also on ARMv7. This does not bring any kind of benefit.
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.

Changes since v3:
1. Rebase on next-20160127.
Changes since v2:
1. Follow Arnd's advice making EXYNOS_ARM64_COMMON_CLK user-visible when
COMPILE_TEST is enabled.
2. Dropped accumulated tags because the logic is now different.
Changes since v1:
1. Use one Kconfig symbol for clocks of all ARM64 SoCs (after
discussion): EXYNOS_ARM64_COMMON_CLK.
2. Minor cleanups after Tomasz's comments.
3. Added tags: Chanwoo's, Sylwester's, Alim's and Tomasz's (the tags
were given for v1 but assuming that change from 1. is not major
enough to require re-tagging).
