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. ]
