From: Weiwei Li <liwei...@iscas.ac.cn> Using implicitly enabled extensions such as Zca/Zcf/Zcd instead of their super extensions can simplify the extension related check. However, they may have higher priv version than their super extensions. So we should mask them in the isa_string based on priv version to make them invisible to user if the specified priv version is lower than their minimal priv version.
