There is a log message "no parameters" for each regulator. This is printed
unconditionally from print_constraints().

Looking through the code again, looks like this is on purpose. It is just a bit
annoying to get lots of those messages. One of the systems I am dealing with has
17 LTC2978 chips in it, with 8 channels each. That results in 136 times "no
parameters" in the boot log. And that is not even a fully populated system;
if fully populated, there can be more than 60 of those chips. 500+ lines of
similar log messages is really a bit on the high side.

It might help if there was a way to silence the messages, ie to make
"print_constraints" optional.
