x86/mce/amd, EDAC/mce_amd: Move long names to decoder module

The long names of the SMCA banks are only used by the MCE decoder
module.

Move them out of the arch code and into the decoder module.

  [ bp: Name the long names array "smca_long_names", drop local ptr in
    decode_smca_error(), constify arrays. ]
