These messages appear each time the mouse wakes from sleep, in my case
(Logitech M705), every minute or so.
Let's downgrade them to the "debug" level so they don't fill the kernel log
by default.

While we are at it, let's make clear that this is a wheel multiplier (and
not, for example, XY movement multiplier).

I have seen this being useful in some cases, however I do not have a
strong opinion on it. Peter would know better.

Well, the message is not being removed, only hidden by default, so
it doesn't fill the kernel log.

One can still enable it at runtime if wanted.

Of course, but instructing users to do that can be annoying, especially
when you're handling a considerable volume of reports.

Anyway, I am fine with this patch, I just thought it was pertinent to
raise this point and maybe get Peter's input on this, as he will likely
be one most affected by it :)
