You mean to ignore ARM/64 SoCs?

Agreed just the below enum, should do the trick.

            - enum:
                - renesas,r9a07g043u11
                - renesas,r9a07g043u12
                - renesas,r9a07g044c1
                - renesas,r9a07g044c2
                - renesas,r9a07g044l1
                - renesas,r9a07g044l2
                - renesas,r9a07g054l1
                - renesas,r9a07g054l2

Yes I have run the dtbs_check and dt_binding _check for ARM64 and
RISC-V. Do you see any cases where it can fail?
