[PATCH 1/3] dt-bindings: spi: renesas,rspi: Document RZ/G2L SoC

[Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>]

Add RSPI binding documentation for Renesas RZ/G2L SoC.

RSPI block is identical to one found on RZ/A, so no driver changes are
required the fallback compatible string "renesas,rspi-rz" will be used
on RZ/G2L
