Documentation: embargoed-hardware-issues.rst: add AMD to the list

Add AMD back to the embargoed-hardware-issues.rst list.  There was
confusion about a recent issue that ended up being due to third-party's
misrepresentation, not AMD, so add AMD back to the list to get notified
properly as they understand the proper procedures to follow.
