From: Fabio Estevam <festevam@xxxxxxx>
OV2680 has a single data lane MIPI interface.
Document the clock-lanes and data-lanes properties to avoid
the following dt-schema warning:
imx7s-warp.dtb: camera@36: port:endpoint: Unevaluated properties are not allowed ('clock-lanes', 'data-lanes' were unexpected)
from schema $id: http://devicetree.org/schemas/media/i2c/ovti,ov2680.yaml#
While at it, also document the link-frequencies property as recommended
by the following document:
https://www.kernel.org/doc/html/v6.9-rc1/driver-api/media/camera-sensor.html#handling-clocks

Changes since v1:
- Keep the existing 'additionalProperties: false'. (Krzysztof)
- Also document link-frequencies.
