Looks accidental in that a merge conflict was resolved differently https://github.com/riscv-software-src/riscv-unified-db/pull/295/files#diff-7a92913cf5c64263aa47e0816cae702ce9c54950ea0227fcc2d74c6d19f5d946L29

I've put potential PR into fix this here: https://github.com/riscv-software-src/riscv-unified-db/pull/374/files
