    iommu/ipmmu-vmsa: Remove redundant of_iommu_init_fn hook
    
    Having of_iommu_init() call ipmmu_init() via ipmmu_vmsa_iommu_of_setup()
    does nothing that the subsys_initcall wouldn't do slightly later anyway,
    since probe-deferral of masters means it is no longer critical to
    register the driver super-early. Clean it up.
