[PATCH v4 5/9] media: dt-bindings: chrontel,ch7322: reference common CEC properties

[Krzysztof Kozlowski]

Reference common HDMI CEC adapter properties to simplify the binding and
have only one place of definition for common properties.  The common CEC
binding expects also node name to be 'cec'.

Changes since v1:
1. Fix node name to cec.
