Subject: [PATCH v3] dt-bindings: serial: renesas: Document RZ/V2N SCIF

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Document SCIF bindings for the Renesas RZ/V2N (a.k.a R9A09G056) SoC.
The SCIF interface in Renesas RZ/V2N is identical to the one available
in RZ/V2H(P), so `renesas,scif-r9a09g057` will be used as a fallback,
allowing reuse of the existing driver without modifications.
