iommu: Remove domain_init and domain_free iommu_ops
All drivers have been converted to the new domain_alloc and domain_free iommu-ops. So remove the old ones and get rid of iommu_domain->priv too, as this is no longer needed when the struct iommu_domain is embedded in the private structures of the iommu drivers.
