iommu/core: Add bus_type parameter to iommu_domain_alloc
This is necessary to store a pointer to the bus-specific iommu_ops in the iommu-domain structure. It will be used later to call into bus-specific iommu-ops. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Conflicts: drivers/iommu/iommu.c Change-Id: Iddbd561739552b663a4be293f1992314eb0f775a
