Revert "cpufreq: schedutil: Move max CPU capacity to sugov_policy"

This reverts commit 6d5afdc97ea71958287364a1f1d07e59ef151b11.

On a Pixel 6 device, it is observed that this commit increases
latency by approximately 50ms, or 20%, in migrating a task
that requires full CPU utilization from a LITTLE CPU to Fmax
on a big CPU. Reverting this change restores the latency back
to its original baseline value.
