iommu/amd: Init unity mappings only for dma_ops domains
commit b548e786ce47017107765bbeb0f100202525ea83 upstream.
The default domain for a device might also be
identity-mapped. In this case the kernel would crash when
unity mappings are defined for the device. Fix that by
making sure the domain is a dma_ops domain.
