I think this is already referenced for all child nodes of a SPI
controller because of pattern matching of:

patternProperties:
  "^.*@[0-9a-f]+$":
    type: object
    $ref: spi-peripheral-props.yaml

in Documentation/devicetree/bindings/spi/spi-controller.yaml

So perhaps not strictly necessary?

Would be curious to know if there is some difference.
