drm/exynos: fimd: clear channel before enabling iommu If any fimd channel was already active, initializing iommu will result in a PAGE FAULT (e.e. u-boot could have turned on the display and not disabled it before the kernel starts). This patch checks if any channel is active before initializing iommu and disables it.
