[PATCH] dt-bindings: remoteproc: xlnx,zynqmp-r5fss: add missing "additionalProperties" on child nodes

[Krzysztof Kozlowski]

All nodes need an explicit additionalProperties or unevaluatedProperties
unless a $ref has one that's false.  Add missing additionalProperties
to fix dt_binding_check warning:

  xlnx,zynqmp-r5fss.yaml: ^r(.*)@[0-9a-f]+$: Missing additionalProperties/unevaluatedProperties constraint

Fixes: 9e1b2a0757d0 ("dt-bindings: remoteproc: Add Tightly Coupled Memory (TCM) bindings")
