[Severity: Low]
Is it possible to add unevaluatedProperties: false to this object?

The Device Tree schema meta-schema strictly requires that any node defined as
type: object must specify either additionalProperties: false or
unevaluatedProperties: false. 

Omitting this on the ^pse-pi@[0-3]$ node causes the schema to silently allow
any undocumented or misspelled property inside the pse-pi@X nodes, which
defeats the purpose of dt-schema validation. Since this node relies on
properties defined in the referenced pse-controller.yaml, using
unevaluatedProperties: false seems to be needed here.
