[PATCH v4 04/14] coresight: export coresight_timeout and etm_perf_symlink

[Kim Phillips <kim.phillips@arm.com>]

Export these symbols for use by other coresight components,
so they can be built as modules.

coresight_timeout is used by the coresight stm, etm4x, tmc,
tpiu, and etb10 modules, and etm_perf_symlink is needed by
the etm3x/4x modules.
