drm/exynos: Use selected dma_dev default iommu domain instead of a fake one

Browse source

Instead of allocating a fake IOMMU domain for all Exynos DRM components,
simply reuse the default IOMMU domain of the already selected DMA device.
This allows some design changes in IOMMU framework without breaking IOMMU
support in Exynos DRM.
