Add data-lanes property support to the port@1 endpoint for physical
lane mapping configuration.

Lane mapping is mainly used for below scenarios:
1. Correct PCB lane swap and differential line routing crossover
without hardware changes;
2. Adapt mismatched lane pin definitions between SoC and eDP panel;
3. Support multiple panel hardware variants on the same board
by configuring data-lanes in device tree only.

Sashiko complaint here looks valid.

Yes, unevaluatedProperties: false should be added to both the port@1
and endpoint nodes.

Will fix in v3.

Best regards,
Damon

Changes in v2:
- Add lane mapping application scenarios in commit message.
- Remove redundant deprecated property 'data-lanes' for eDP node.
- Update port@1 $ref to /schemas/graph.yaml#/$defs/port-base.
