x86/MCE/AMD, EDAC/mce_amd: Add new McaTypes for CS, PSP, and SMU units
The existing CS, PSP, and SMU SMCA bank types will see new versions (as indicated by their McaTypes) in future SMCA systems. Add the new (HWID, MCATYPE) tuples for these new versions. Reuse the same names as the older versions, since they are logically the same to the user. SMCA systems won't mix and match IP blocks with different McaType versions in the same system, so there isn't a need to distinguish them. The MCA_IPID register is saved when logging an MCA error, and that can be used to triage the error. Also, add the new error descriptions to edac_mce_amd. Some error types (positions in the list) are overloaded compared to the previous McaTypes. Therefore, just create new lists of the error descriptions to keep things simple even if some of the error descriptions are the same between versions.
