Subject: [PATCH] drivers/hwtracing: add missing header dependencies

We get 1 warning when building kernel with W=1:
drivers/hwtracing/coresight/coresight-etm-perf.c:345:5: warning: no previous prototype for 'etm_perf_symlink' [-Wmissing-prototypes]

In fact, this function is declared in coresight-etm-perf.h, so this patch
add missing header dependencies.
