A seperate bus_type instance is not required for Exynos5. The existing bus_type
instance used with Exynos4 is sufficient for both Exynos4 and Exynos5. This
also solves issue of uninitialized usage of exynos4_subsys in Exynos4 power
management code that is reused for Exynos5 also. In addition to that, the
existing exynos4_subsys bus_type is renamed to exynos_subsys to indicate that
it is reused on both Exynos4 and Exynos5 platforms.
