arm64: device: add iommu pointer to device archdata
When using an IOMMU for device mappings, it is necessary to keep a pointer between the device and the IOMMU to which it is attached in order to obtain the correct IOMMU when attaching the device to a domain. This patch adds an iommu pointer to the dev_archdata structure, in a similar manner to other architectures (ARM, PowerPC, x86, ...).
