[PATCH v2 20/23] coresight: trbe: Add fault action argument to trbe_handle_overflow()

[Leo Yan]

Add a new argument to trbe_handle_overflow() for the fault action, which
is used to compare the wrap event for trace size calculation.

No functional change intended; this is preparation for a later update.
