[PATCH net] dt-bindings: net: pse-pd: ti,tps23881: Fix missing "additionalProperties" constraints

["Rob Herring (Arm)" <robh@kernel.org>]

The child nodes are missing "additionalProperties" constraints which
means any undocumented properties or child nodes are allowed. Add the
constraints and all the undocumented properties exposed by the fix.

Fixes: f562202fedad ("dt-bindings: net: pse-pd: Add bindings for TPS23881 PSE controller")
Signed-off-by: Rob Herring (Arm) <robh@kernel.org>
