They're visible to a user that has #defined DEBUG.  They're something
one might want to grep on.  checkpatch.pl explicitly considers
pr_debug/dev_dbg to be part of the set of functions that can go over the
limit (it just doesn't know about U-Boot's plain old "debug()").  But
whatever...

At some point you might want to consider actually writing down your
interpretations of these things into a U-Boot coding style document, so
at least we don't have to guess.
