iommu: Add IOMMU_DOMAIN_PLATFORM for S390
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.
