rasdaemon: add support for new AMD SMCA bank types
Going forward, the Scalable Machine Check Architecture (SMCA) has some
updated and additional bank types which show up in Zen2. The differing
bank types include: CS_V2, PSP_V2, SMU_V2, MP5, NBIO, and PCIE. The V2
bank types replace the original bank types but have unique HWID/MCAtype
IDs from the originals so there's no conflicts between different
versions or other bank types. All of the differing bank types have new
MCE descriptions which have been added as well.
