[PATCH 3/5] iommu/vt-d: Remove unused dma map/unmap trace events

[Lu Baolu]

With commit c588072bba6b5 ("iommu/vt-d: Convert intel iommu driver to
the iommu ops"), the trace events for dma map/unmap have no users any
more. Remove them so that they don't show up under
/sys/kernel/debug/tracing/events/intel_iommu. The users should use the
map/unmap traces defined in the iommu core from now on.

Fixes: c588072bba6b5 ("iommu/vt-d: Convert intel iommu driver to the iommu ops")
