…ras/ras into x86/ras

Pull x86 RAS changes from Borislav Petkov:

 "Rework all config variables used throughout the MCA code and collect
  them together into a mca_config struct. This keeps them tightly and
  neatly packed together instead of spilled all over the place.

  Then, convert those which are used as booleans into real booleans and
  save some space."
