Cortex-A710: 2054223: workaround TSB instruction failing to flush trace

configname: CONFIG_ARM64_ERRATUM_2054223

Enable workaround for ARM Cortex-A710 erratum 2054223

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.
