Jason Gunthorpe fae6e669cd drm/tegra: Do not assume that a NULL domain means no DMA IOMMU ...

Previously with tegra-smmu, even with CONFIG_IOMMU_DMA, the default domain
could have been left as NULL. The NULL domain is specially recognized by
host1x_client_iommu_attach() as meaning it is not the DMA domain and
should be replaced with the special shared domain.

This happened prior to the below commit because tegra-smmu was using the
NULL domain to mean IDENTITY.

Now that the domain is properly labled the test in DRM doesn't see NULL.
Check for IDENTITY as well to enable the special domains.

Fixes: c8cc2655cc ("iommu/tegra-smmu: Implement an IDENTITY domain")
