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

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.
