Note that the target of this move is not .../bindings/soc/, but
.../bindings/soc/renesas/, so it's a bit less of a dumping ground.
Perhaps this is also a good opportunity to split renesas.yaml per
family or product group
(renesas,{rmobile,rcar-gen[1234],rza,rzg,rzn,...}.yaml?
A fine-grained split may cause headaches with RZ/G2UL and RZ/Five
sharing the same SoC Base, but a coarse-grained split keeping all RZ/G
(after all RZ/Five is part of RZ/G) or even all RZ series together should work.

.../bindings/board has the issue with the same boards used with
multiple pin-compatible SoCs, SiPs, and SoMs.
