Blackfin: remove CONFIG_DEBUG_VERBOSE from trace.c

Browse Source 
Now that the split traps code has moved all the verbose output to the
trace.c file, we can unify all the CONFIG_DEBUG_VERBOSE handling.  This
gets rid of much of the crappy ifdef forest and enables usage of normal
pr_xxx functions so checkpatch stops complaining.
