Fixing the compatible string typos results in an error in the example:

Documentation/devicetree/bindings/iommu/renesas,ipmmu-vmsa.example.dt.yaml:
  iommu@fe951000: 'power-domains' is a required property

Based on the dts files, a 'power-domains' property only exists on Gen 3
which can be conditioned on !renesas,ipmmu-vmsa.
