rS367725: Add device_t member to struct iommu.

Summary

Add the device field to struct iommu.

This is needed on arm64 for the interface between iommu framework and drivers (i.e. SMMU).
We have multiple instances of SMMU on arm64.

Example:
error = IOMMU_MAP(iommu->dev, iodom, va, ma, size, prot);
