The PLATFORM domain will be set as the default domain and attached as normal during probe. The driver will ignore the initial attach from a NULL domain to the PLATFORM domain. After this, the PLATFORM domain's attach_dev will be called whenever we detach from an UNMANAGED domain (eg for VFIO). This is the same time the original design would have called op->detach_dev(). This is temporary until the S390 dma-iommu.c conversion is merged.
