[PATCH v2 1/4] i386/cpu: Add RAS feature bits on EPYC CPU models

[Babu Moger]

Add the support for following RAS features bits on AMD guests.

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.

McaOverflowRecov: MCA overflow recovery support.
