Hi,

Third attempt to remove ARCH_EXYNOS7 symbol.

Patches cannot be cherry-picked. I was thinking about merging this
through arm-soc tree after getting needed acks (clk, arm-soc?).


Changes since v2:
=================
1. Follow Arnd's advice about not enabling silently the newly added
   EXYNOS_ARM64_COMMON_CLK, when COMPILE_TEST is enabled. This was
   also a trigger for some changes in placement of Samsung clocks
   Kconfig entries...
2. ... which lead to introducing patch 1.


Logic:
======
Now the clock selection algorithm works like:
1. For Exynos ARMv7 and ARMv8 the platforms select COMMON_CLK
   and COMMON_CLK_SAMSUNG.
2. As before: clock drivers for Exynos ARMv7 will be selected by
   respective SOC/ARCH_EXYNOS_XXX symbol.
3. For Exynos ARMv8 the clock drivers will be enabled by default
   by EXYNOS_ARM64_COMMON_CLK symbol.

Rationale:
==========
We don't need ARCH_EXYNOS7 symbol because all ARMv8 platforms should
fall under generic ARCH_EXYNOS. In the same time there is no sense
in building clocks for these ARMv8 SoCs on ARMv7 builds. In future
this will also influence PMU [1] driver.


Best regards,
Krzysztof
