[PATCH 2/6] dt-bindings: display: armada: Improve the LCDC documentation

[Lubomir Rintel <lkundrak@v3.sk>]

The port is a child, not a property. And it deserves an example.

Also, make the title a bit more visually distinguishable -- this will
look better when the documentation of other Adrmada DRM nodes will be
present.
