x86: Update CPU cache attributes table descriptors 

Update to latest definitions in:

   http://www.intel.com/Assets/PDF/appnote/241618.pdf



[ Note, this update of the doc has removed some old values which
  we have listed.  I think until we have clarification that they
  were never used in production, they should be left there. ]
