There's so much scaler debugging messages that it makes other debugging
hard. Remove them.

I had some patches for this, especially "[PATCH] drm/i915/skl: Only
disable scalers once" which I couldn't test properly due lack of
hardware. And "[PATCH] drm/i915/skl: Bypass debug message if scalers are
not requested", which only silences the case when scalers are not in
use, so yours may even be better.
But for the former, I think someone who knows this code should look at
my patch. To me it looks warranted to skip disabling scalers if they are
already disabled, rather than just kill the debug message.
