ARM: EXYNOS: Add clock register addresses for EXYNOS4X12 bus devfreq driver
ARM: EXYNOS: add clock registers for exynos4x12-cpufreq
PM / devfreq: update the name of EXYNOS clock registers that were omitted
PM / devfreq: update the name of EXYNOS clock register
ARM: EXYNOS: change the prefix S5P_ to EXYNOS4_ for clock
ARM: EXYNOS: use static declaration on regarding clock
ARM: EXYNOS: replace clock.c for other new EXYNOS SoCs
