[PATCH v3 03/13] sandbox: Add a fake DSI controller and link it to the panel

[Miquel Raynal]

Use a graph endpoint representation for that in order to test a new core
DM helper going through these properties.

Display pipelines typically include graph endpoints, but the helper is
generic and would work with any device type.
