Various boards that use the rt5640 audio codec define a 'port' child node under the codec node to describe the interface between it and the SoC that it is connected to. The binding document for the rt5640 codec does not define the 'port' child node and so this is generating warnings when running the DTB checks for these boards. Add the 'port' node to the binding document for the rt5640 codec to fix this.
