powerpc: Add iommu domain pointer to device archdata
Add an iommu domain pointer to device (powerpc) archdata. Devices are attached to iommu domains and this pointer provides a mechanism to correlate between a device and the associated iommu domain. This field is set when a device is attached to a domain.
