Driver core: Add iommu_ops to bus_type
This is the starting point to make the iommu_ops used for the iommu-api a per-bus-type structure. It is required to easily implement bus-specific setup in the iommu-layer. The first user will be the iommu-group attribute in sysfs. Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
