Trigger field ignore_default was changed to override_trig. The first byte of the field indicates the driver to override existing configuration or keep the previous one The second byte of the field indicated the driver to replace the regions of the previous trigger or to append new regions to it. Change the way the active triggers are maintained to support trigger override in different apply points. Do this by making a trigger that updates at runtime by the triggers that are being used in the different apply points. In case of an assert, the driver does not reconfigure the triggers and uses the old configuration which leads to undefined behavior. Solve this by clearing the triggers in assert recovery flow.
