Control bits for clock gating of System MMU MFC L/R is inversed in clock-exynos5.c
The following patch is the fix of the problem for 03/12 patch.
Thanks to Prathyush.

Subject: [PATCH 03/12] ARM: EXYNOS: remove system mmu initialization from exynos tree
This removes System MMU initialization from arch/arm/mach-exynos/
to move them to DT and the exynos-iommu driver except gating clock
definitions.
