[PATCH 5.10.y-cip 12/18] media: dt-bindings: media: renesas,vsp1: Document RZ/G2L VSPD bindings

[Biju Das <biju.das.jz@bp.renesas.com>]

commit 17b5179ef6cd6430945c1da4174ceaf43c93cf1e upstream.

Document VSPD found in RZ/G2L SoC. VSPD block is similar to VSP2-D
found on R-Car SoC's, but it does not have a version register and
it has 3 clocks compared to 1 clock on vsp1 and vsp2.

This patch introduces a new compatible 'renesas,r9a07g044-vsp2' to
handle these differences.
