Subject: [PATCH v4 2/9] dt-bindings: soc: renesas: Add RZ/G3E variant SYS binding

Add RZ/G3E (R9A09G047) variant to the existing RZ/V2H System Controller
(SYS) binding as both IPs are compatible.

They however have different SoC IDs, RZ/G3E has VSP control register
compared to RZ/V2H SYS IP. Hence a new compatible string
renesas,r9a09g047-sys introduced to handle these differences.

    v1: Reviewed-by: Geert Uytterhoeven <geert+renesas@...der.be>
    v2: Tags dropped due to small changes in compatible property structure.
