[PATCH v2 2/3] iommu/ipmmu-vmsa: Remove redundant of_iommu_init_fn hook

[robin.murphy@arm.com (Robin Murphy)]

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.

v2: New (somehow v1 was based on 4.14-rc3 so missed this...)
