We're going to include one case with the 'max' CPU where env->vext_ver will be set in the cpu_init(). But that alone will not stop the "vector version is not specified" message from appearing. The usefulness of this log message is debatable for the generic CPUs, but for a 'max' CPU type, where we are supposed to deliver a CPU model with all features possible, it's strange to force users to set 'vext_spec' to get rid of this message. Change riscv_cpu_validate_v() to not throw this log message if env->vext_ver is already set.
