[PATCH] media: dt-bindings: ovti,ov2680: Document clock/data-lanes

[Fabio Estevam <festevam@xxxxxxxxx>]

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#
