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

[Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>]

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.
