of: iommu: make of_iommu_init() postcore_initcall_sync
The of_iommu_init() is called multiple times by arch code, make it postcore_initcall_sync, then we can drop relevant calls fully. Note, the IOMMUs should have a chance to perform some basic initialisation before we start adding masters to them. So postcore_initcall_sync is good choice, it ensures of_iommu_init() called before of_platform_populate.
