x86/mce, EDAC/mce_amd: Print MCA_SYND and MCA_IPID during MCE on SMCA systems
The MCA_SYND and MCA_IPID registers contain valuable information and
should be included in MCE output. The MCA_SYND register contains
syndrome and other error information, and the MCA_IPID register will
uniquely identify the MCA bank's type without having to rely on system
software.
