Subject[PATCH v2 3/3] coresight: Update comments for removing cs_etm_find_snapshot()
Date
Since the function cs_etm_find_snapshot() has been removed in the user
space, it directly uses the perf common function __auxtrace_mmap__read()
to calcualte the head and size for AUX trace data in snapshot mode.

Updates the comments in drivers to reflect the changes.
