Add DT bindings for the hdmi driver for the Ingenic JZ4780 SoC.
Based on .txt binding from Zubair Lutfullah Kakakhel

We also add add generic ddc-i2c-bus to synopsys,dw-hdmi.yaml

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:
./Documentation/devicetree/bindings/display/ingenic-jz4780-hdmi.yaml:36:5: [warning] wrong indentation: expected 2 but found 4 (indentation)

dtschema/dtc warnings/errors:

	From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/display/ingenic-jz4780-hdmi.yaml

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/1553577

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

This goes in display/bridge/. And use compatible string for the file 
name: ingenic,jz4780-hdmi.yaml

I think you need to use 'unevaluatedPropertes' instead of 
'additionalProperties' if you are getting these properties from 
synopsys,dw-hdmi.yaml.
