dt-bindings: display: bridge: analogix-dp: Add data-lanes support for endpoint
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.
Additionally, add data-lanes setting in Rockchip eDP DT node example
to show actual lane mapping usage.
