[PATCH v4 2/5] dt-bindings: media: qcom,sm8250-camss: allow JPEG encoder child node

[Atanas Filipov]

The CAMSS node uses #address-cells = <2>, #size-cells = <2> and ranges
to act as a bus for child IP blocks such as the JPEG encoder. Add these
properties to the binding so that dtbs_check does not reject them.

Use unevaluatedProperties: false instead of additionalProperties: false
so that child nodes are validated against their own schema (matched by
compatible) without requiring the parent binding to enumerate each child
type explicitly. This is the correct approach for a bus-like container
node and avoids updating the camss binding for every new child device
added in the future.

No functional change.
