The fact that `max_fifo' contains max FIFO depth is already coded in
the variable name itself. And with that new FIFO_DEPTH() macro, it
would be basically stating the same thing the third time on the same
string. Thought the removal of that comment only made the code easier
to read. If you think I should bring the comment back, please let me
know and I'll send v2.
