x86/MCE/AMD, EDAC/mce_amd: Add new SMCA bank types
Add HWID and McaType values for new SMCA bank types, and add their error descriptions to edac_mce_amd. The "PHY" bank types all have the same error descriptions, and the NBIF and SHUB bank types have the same error descriptions. So reuse the same arrays where appropriate.
