Borislav Petkov (AMD) ed9b87010a x86/cpu/amd: Add a Zenbleed fix
Upstream commit: 522b1d6921

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.
