sched/cpufreq: fix tunables for schedfreq governor
The schedfreq governor does not currently handle cpufreq drivers which
use a global set of tunables (!have_governor_per_policy).
For example on x86 and using the acpi cpufreq driver, doing this
cat /sys/devices/system/cpu/cpufreq/sched/up_throttle_nsec
will result in a bad pointer access.
Update the tunable code using the upstream schedutil tunable code by
Rafael Wysocki as a guide.
Includes a partial backport of the reorganized cpufreq tunable
infrastructure.
