Subject: [PATCH v1 1/4] clk: samsung: change COMMON_CLK_SAMSUNG default config logic

COMMON_CLK_SAMSUNG is selected by ARCH_EXYNOS which forces this config
to be built-in when ARCH_EXYNOS is enabled. Switch the logic to use a
"default y if ARCH_EXYNOS" to provide flexibilty for vendors to disable
or modularize this driver.

I verified the .config is identical with and without this change.
