Subject: [PATCH v2 3/3] dt-bindings: mtd: spi-nor: Add a reference to spi-slave-props.yaml

The spi-slave-props.yaml schema contains slave-specific properties
for SPI controllers that should be present in the slave node. Add a
reference to that so its constraints are followed.

additionalProperties: false cannot be used since it marks the controller
properties as unknown. Use unevaluatedProperties: false instead. This
has the side effect of allowing extra properties that are not specified
in the schema. The alternative is to list all the controller properties
in this schema but that would mean every slave binding would have to
repeat the same set of properties for each controller.
