    x86/cpu/amd: Add a Zenbleed fix
    
    commit 522b1d69219d8f083173819fde04f994aa051a98 upstream.
    
    Add a fix for the Zen2 VZEROUPPER data corruption bug where under
    certain circumstances executing VZEROUPPER can cause register
    corruption or leak data.
    
    The optimal fix is through microcode but in the case the proper
    microcode revision has not been applied, enable a fallback fix using
    a chicken bit.
