[PATCH 2/3 v4] drm/panel: Add DT bindings for Sony ACX424AKP

[Linus Walleij]

This adds device tree bindings for the Sony ACX424AKP panel.
Let's use YAML.

ChangeLog v3->v4:
- Adjust to adjusted DSI bindings.
ChangeLog v2->v3:
- Put the example inside a dsi-controller so we have a complete
  example that verifies to the DSI panel generic binding.
ChangeLog v1->v2:
- Suggest a stand-alone YAML bindings file for DSI panels in
  a separate patch, and use that to reference the
  boolean "enforce-video-mode" attribute for DSI panels
