cxl/trace: Add an HPA to cxl_poison trace events
When a cxl_poison trace event is reported for a region, the poisoned
Device Physical Address (DPA) can be translated to a Host Physical
Address (HPA) for consumption by user space.
Translate and add the resulting HPA to the cxl_poison trace event.
Follow the device decode logic as defined in the CXL Spec 3.0 Section
8.2.4.19.13.
If no region currently maps the poison, assign ULLONG_MAX to the
cxl_poison event hpa field.
