Example of such drivers are the ov2680 and ov5693 drivers. The standard ov5693 sensor also expects a "link-frequencies" property. Add support for setting both properties. Note the "clock-frequency" prop is added before the "rotation" prop while the "link-frequencies" are added at the end to match the ipu3 cio2-bridge code from which this is derived.
