drm/exynos: clear channels only when iommu is enabled This is simplest solution about reported problem[1]. It's no problem to clear channel only when iommu is enabled, if we consider that we cannot recognize iommu errors when iommu is disabled and it have been valid until now. But this cannot be nice solution.
