sched/fair: Remove stale FREQUENCY_UTIL comment

I'm fine with either and that was my first thought here, too, but it did seem like
the comment was mostly placed there to justify the 'unexpected' high utilization
when explicitly passing FREQUENCY_UTIL and the need to clamp it then.

Subject: [PATCH] sched/fair: Remove stale FREQUENCY_UTIL mention
effective_cpu_util() flags were removed, so remove mentioning of the
flag.
commit 9c0b4bb7f6303 ("sched/cpufreq: Rework schedutil governor performance estimation")
reworked effective_cpu_util() removing enum cpu_util_type. Modify the
comment accordingly.
