Add another flag for debugging just peripheral drivers. The whole debugging

Browse Source 
mechanism should be completely  revamped, but this will serve for the time
being.

Take advantage of some new behavior in xpt_path_comp which allows the
caller to determine which path, if any, had wildcards in it that allowed
for a match to succeed.  We can now use this to filter out wildcard
nodes in the EDT.

Make the amount of time we pause after writing a debug message
configurable.
