Log:
Add some basic KTR tracing to busdma on i386. This is likely not
the final set of traces -- someone with more busdma background
will probably want to review and expand this, as well as port to
other platforms. This tracing is sufficient to identify key
busdma events on i386, and in particular to draw attention to
bounce buffering events that may have a substantial performance
impact.
