[3/8] dt-bindings: display: renesas, lvds: Add LVDS binding for D3

From: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com>

The D3 supports two LVDS channels. Extend the binding to support them.

Hi Laurent,

Are we unable to have a generic lvds-gen3 here?

(Although to perhaps answer my own question I see that the D3/E3 have extra
registers)

Also "lets pretend" that I intentionally separated out the LVDS updates to the
rcar_lvds_of_table :)

Hi Kieran,

Thank you for the patch.

This should be "renesas,r8a77995-lvds". I've already fixed the series you've 
based this patch on.

Apart from this,

Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

and taken in my tree with the compatible string fixed.

We could for H3 and M3-W, but as you've noticed D3/E3 differ, and so does V3M.
