…ld get the wrong debug_cause. This would happen if a synchronous debug reason was in WB at the same time, the taken NMI/interrupt would kill WB but that was not reflected in the debug cause. Signed-off-by: Oystein Knauserud <Oystein.Knauserud@silabs.com>
…pt + single step. SEC clean if an ebreak with dcsr.ebreakm is not flagged as an exception. Bugfix for not flagging ebreak as exception if dcsr.ebreakm is set will come in a separate PR. Signed-off-by: Oystein Knauserud <Oystein.Knauserud@silabs.com>

A new merge will be done shortly which will add privilege level checks to the exception detection for ebreaks. This will better align the sources between X and S and enable a full fix on e40s for the exception/ebreak depending on dcsr.ebrakm and dcsr.ebreaku.
