Let's introduce a helper function aiming at recording an
event in the event queue.
Signed-off-by: Eric Auger <eric.au...@redhat.com>
---
v8 -> v9:
- add SMMU_EVENT_STRING
v7 -> v8:
- use dma_addr_t instead of hwaddr in smmuv3_record_event()
- introduce struct SMMUEventInfo
- add event_stringify + helpers for all fields
