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.

i.e. will queue in renesas-devel for v6.15.
