[PATCH v1 1/1] dt-bindings: fix simple-framebuffer example

[Sam Ravnborg <sam@xxxxxxxxxxxx>]

Now that dt-extract-example gained support for using root nodes
in examples, update the example for the simple-frambuffer binding to use it.

This gives us a better example and kill a long standing warning:

simple-framebuffer.example.dts:23.16-39.11:
Warning (chosen_node_is_root): /example-0/chosen: chosen node must be at root node

Note: To get the update dt-extract-example execute:
pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade
