sched/uclamp: Remove uclamp_util()

The sole user of uclamp_util(), schedutil_cpu_util(), was made to use
uclamp_util_with() instead in commit:

  af24bde8df20 ("sched/uclamp: Add uclamp support to energy_compute()")

From then on, uclamp_util() has remained unused. Being a simple wrapper
around uclamp_util_with(), we can get rid of it and win back a few lines.
