We're doing env->priv_spec validation and assignment at the start of riscv_cpu_realize(), which is fine, but then we're doing a force disable on extensions that aren't compatible with the priv version. This second step is being done too early. The disabled extensions might be re-enabled again in riscv_cpu_validate_set_extensions() by accident. A better place to put this code is at the end of riscv_cpu_validate_set_extensions() after all the validations are completed. Add a new helper, riscv_cpu_disable_priv_spec_isa_exts(), to disable the extesions after the validation is done. While we're at it, create a riscv_cpu_validate_priv_spec() helper to host all env->priv_spec related validation to unclog riscv_cpu_realize a bit.
