We do have the uclamp doc now which explains this, no? I'm not keen on
utilization because it's an overloaded term. In the context of uclamp
- utilization _signal_ in the scheduler is used to indicate performance
requirements of a workload, no?

Using 'uclamp hint' if you found it really confusing, is fine by me. But I'd
rather steer away from 'bandwidth' or 'utilization' when describing uclamp and
its intention.

I like using performance requirements because it enforces what this hint
actually means.
