[06/16] dt-bindings: serial: renesas,scif: Document RZ/V2L SoC

From: Biju Das <biju.das.jz@bp.renesas.com>

Add SCIF binding documentation for Renesas RZ/V2L SoC. SCIF block on RZ/V2L
is identical to one found on the RZ/G2L SoC. No driver changes are required
as RZ/G2L compatible string "renesas,scif-r9a07g044" will be used as a
fallback.

As the idea is to rely on the RZ/G2L fallback for matching, cfr. below,
the above addition is not needed or wanted.

This addition is not needed if the fallback is always present.

Given Greg already applied your patch, I think you have to send a
follow-up patch.
Thanks!
