iommu: Change iommu driver to call detach_device_to_domain trace event
Change iommu driver to call detach_device_to_domain trace event. This
iommu_device class event can be enabled to trigger when devices are detached
from a domain. Trace information includes device name.
Testing:
Added trace calls to iommu_prepare_identity_map() for testing some of the
conditions that are hard to trigger. Here is the trace from the testing:
swapper/0-1 [003] .... 1.854102: detach_device_from_domain: IOMMU: device=0000:00:02.0
