dt-bindings: serial: renesas,rsci: Document RZ/V2H(P) and RZ/V2N SoCs

Document the serial communication interface (RSCI) used on the Renesas
RZ/V2H(P) (R9A09G057) and RZ/V2N (R9A09G056) SoCs. These SoCs integrate
the same RSCI IP block as the RZ/G3E (R9A09G047), so the RZ/G3E
compatible is used as a fallback for both.
