Enable the Bus Lock Detect feature for the EPYC-Turin-v2 CPU model to
match the hardware capabilities of AMD Turin processors. This feature
allows detection of split locks and bus locks, which can cause
performance degradation in multi-core systems.

The bus-lock-detect feature is part of the architectural capabilities
exposed through CPUID and should be enabled by default for Turin v2
and later CPU models.
