[PATCH v2] media: dt-bindings: media: renesas,csi2: Update data-lanes property

[Lad Prabhakar]

CSI-2 (CSI4LNK0) on R-Car and RZ/G2 supports 4-lane mode which is already
handled by rcar-csi2.c driver. This patch updates the data-lanes property
to describe the same.

Hi All,

Instead of adding uniqueItems:true into SoC binding doc's I think we could
add this in video-interfaces.yaml for data-lanes property. Any thoughts on this?

Cheers,
Prabhakar

v1->v2
* Dropped const items
* Added uniqueItems
