That's a point worth discussing with Peter, we already changed one
time from percentages to 1024 scale.

Utilization clamps are expressed as percentages by definition,
they are just expressed in a convenient 1024 scale which should not be
alien to people using those knobs.

If we wanna use a "more specific" name like uclamp.{min,max} then we
should probably also accept to use a "more specific" metric, don't we?

I personally like the [0..1024] range, but I guess that's really up to
you and Peter to agree upon.
