The SchedTune CPU boosting API is currently used from sugov_get_util()
to get the boosted utilization and to pass it into schedutil_cpu_util().
When UtilClamp is in use instead we call schedutil_cpu_util() by
passing in just the CFS utilization and the clamping is done internally
on the aggregated CFS+RT utilization for FREQUENCY_UTIL calls.
This asymmetry is not required moreover, schedutil code is polluted by
non-mainline SchedTune code.
Wrap SchedTune API call related to cpu utilization boosting with a more
generic and mainlinish UtilClamp call:
- uclamp_rq_util_with(cpu, util, p) <= boosted_cpu_util(cpu)
This new API is already used in schedutil_cpu_util() to clamp the
aggregated RT+CFS utilization on FREQUENCY_UTIL calls.
Move the cpu boosting into uclamp_rq_util_with() so that we remove any
SchedTune specific bit from kernel/sched/cpufreq_schedutil.c.
Get rid of the no more required boosted_cpu_util(cpu) method and replace
it with a stune_util(cpu, util) which signature is better aligned with
its uclamp_rq_util_with(cpu, util, p) counterpart.
