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.
