[PATCH v3 7/8] perf cs-etm: Treat EO_TRACE element as trace discontinuity

[Leo Yan <leo.yan@linaro.org>]

If decoder outputs EO_TRACE element, it means the end of the trace
buffer; this is a discontinuity and in this case the end of trace data
needs to be saved.

This patch generates CS_ETM_DISCONTINUITY packet for EO_TRACE element
hereby flushing the end of trace data in cs-etm.c.
