coresight: Unify bus unregistration via coresight_unregister()

Browse source

Once a device is successfully registered, set the "registered" flag to
true.  After that point, all failures jump to the out_unlock label to
unwind the flow via coresight_unregister().

Since failure handling is unified, the comment about resource release
for the etm_perf_add_symlink_sink() failure is no need, remove it.
