[PATCH v2 3/3] drm/exynos: initialize VIDCON0 when fimd is disabled

When the fimd is disabled by fimd_disable(), enabled overlay layers also are disabled. If clocks for fimd are enabled by fimd_enable() on this case, it can lead IOMMU page fault. The reason is that VIDCON0_ENVID and VIDCON0_ENVID_F bits of VIDCON0 register are set still even though fimd is disabled
