dt-bindings: serial: renesas,rsci: Document RZ/N2H support

Browse Source 
Add documentation for the serial communication interface (RSCI) found on
the Renesas RZ/N2H (R9A09G087) SoC. The RSCI IP on this SoC is identical
to that on the RZ/T2H (R9A09G077) SoC. Therefore, "renesas,r9a09g077-rsci"
is used as a fallback compatible string for RZ/N2H.
