drm/exynos: consider no iommu support to console framebuffer
This patch considers no iommu support to kernel space mapping of console framebuffer. Without iommu, we get physical address instead of device address after dma_alloc_attrs function is called. So we should consider the case without iommu when it maps console framebuffer with kernel space. Changelog v2: - calll vunmap function only with iommu support.
