Reorder the tmu_gpu clock initialization for exynos5422 SoC.Why?
It just code reorder

The clock was before taken unconditionally, not within "else" branch...
The whole *clk_sec* ie tmu_triminfo_apbif clock enable is being moved down to the switch case. tmu_triminfo_apbif clock is not used by Exynos4412 and Exynos5433 and Exynos7 SoC.
