Hi Rob,

Convert device tree bindings of graph to YAML format. Currently graph.txt
doc is referenced in multiple files and all of these need to use schema
references. For now graph.txt is updated to refer to graph.yaml.

As per report from 
http://patchwork.ozlabs.org/project/devicetree-bindings/patch/1604075956-17010-2-git-send-email-spujar@nvidia.com 
there are some warnings. I will fix yamllint warnings in v3.

However I don't see below errors when I run 'make dt_binding_check' locally.

dtschema/dtc warnings/errors:
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/graph.yaml: 
'additionalProperties' is a required property
schemas/graph.yaml: ignoring, error in schema:
./Documentation/devicetree/bindings/graph.yaml: Unresolvable JSON 
pointer: 'properties/port'
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/graph.yaml: 
ignoring, error in schema:
warning: no schema found in file: 
./Documentation/devicetree/bindings/graph.yaml

Am I missing anything?

Thanks,
Sameer.
