[PATCH] dc395x [4/5] - debugging cleanup 

Clean up debugging statements. Work on making output consistent - use
the same format each time the same bit of information is output and
output the same bits of information in the same order each time it's
output. Update a lot of the actual messages to include useful
information and to explain better what some things are. Remove some
old comments and commented out code. Remove some of the debugging
states. Find few instance of spaces that should have been tabs and
trailing white space and remove them.
