[PATCH v1 0/1] dt-bindings: fix simple-framebuffer warning

Trivial fix for a long standing warning.
At least not fixed in drm-msc-next for now.
Just in case it was not fixed by someone else (Rob?) already.

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

Why drop the aliases example?

I did not see it had any value for the binding that the example shall
demonstrate. But it was not somthing I have given much thought of.

I don't think anything actually supports 'display' aliases and it is
beyond the scope of this binding, so I'd drop.

stdout-path should be dropped too as it points to this.
