Leo Yan 26701ceb4c coresight: tmc-etr: Add barrier after updating AUX ring buffer
Since a memory barrier is required between AUX trace data store and
aux_head store, and the AUX trace data is filled with memcpy(), it's
sufficient to use smp_wmb() so can ensure the trace data is visible
prior to updating aux_head.
