Neoverse-N2: 2067961: workaround TSB instruction failing to flush trace

Enable workaround for ARM Neoverse-N2 erratum 2067961

Affected cores may fail to flush the trace data on a TSB instruction, when
the PE is in trace prohibited state. This will cause losing a few bytes
of the trace cached.

Workaround is to issue two TSB consecutively on affected cores.

If unsure, say Y.
