[PATCH v3 3/5] dt-bindings: i3c: Make 'assigned-address' valid if static address == 0

[Vitor Soares]

The I3C devices without a static address can require a specific dynamic
address for priority reasons.

Let's update the binding document to make the 'assigned-address' property
valid if static address == 0 and add an example with this use case.
