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

This looks a bit odd. 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.

Best regards,
Krzysztof
Thanks & Regards
