[PATCH] dt-bindings: serial: renesas,scif: Document R9A09G057 support

[Prabhakar]

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

Document support for the Serial Communication Interface with FIFO (SCIF)
available in the Renesas RZ/V2H(P) (R9A09G057) SoC. The SCIF interface in
the Renesas RZ/V2H(P) is similar to that available in the RZ/G2L
(R9A07G044) SoC, with the only difference being that the RZ/V2H(P) SoC has
three additional interrupts: one for Tx end/Rx ready and the other two for
Rx and Tx buffer full, which are edge-triggered.

No driver changes are required as generic compatible string
"renesas,scif-r9a07g044" will be used as a fallback on RZ/V2H(P) SoC.
