x86/MCE/AMD, EDAC/mce_amd: Add new error descriptions for some SMCA bank types

Browse Source 
Some SMCA bank types on future systems will report new error types even
though the bank type is not treated as a new version. These new error
types will reported by bits that are reserved in past systems.

Add the new error descriptions to the lists in edac_mce_amd.
