Following feature bits are added on EPYC-Genoa-v2 model.

perfmon-v2: Allows guests to make use of the PerfMonV2 features.

SUCCOR: Software uncorrectable error containment and recovery capability.
            The processor supports software containment of uncorrectable errors
            through context synchronizing data poisoning and deferred error
            interrupts.
