cxl/memdev: Trace inject and clear poison as cxl_poison events
The cxl_poison trace event allows users to view the history of poison
list reads. With the addition of inject and clear poison capabilities,
users will expect similar tracing.
Add trace types 'Inject' and 'Clear' to the cxl_poison trace_event and
trace successful operations only.
If the driver finds that the DPA being injected or cleared of poison
is mapped in a region, that region info is included in the cxl_poison
trace event. Region reconfigurations can make this extra info useless
if the debug operations are not carefully managed.
