drm/tegra: Optionally attach clients to the IOMMU If a client is already attached to an IOMMU domain that is not the shared domain, don't try to attach it again. This allows using the IOMMU-backed DMA API. Since the IOMMU-backed DMA API is now supported and there's no way to detach from it on 64-bit ARM, don't bother to detach from it on 32-bit ARM either.
