Subject: [PATCH v1 2/4] soc: samsung: change SOC_SAMSUNG default config logic

Switch the default logic to enable SOC_SAMSUNG and it's sub-configs to
be enabled by default via "default y if ARCH_EXYNOS" versus being
selected by the ARCH_EXYNOS config directly. This allows vendors to
disable these configs if they wish and provides additional flexibility
to modularize them in the presence of a generic kernel.

There are no .config differences with this change. The configs
SOC_SAMSUNG, EXYNOS_CHIPID, EXYNOS_PM_DOMAINS, and EXYNOS_PMU still
remain enabled by default.
