Steve Muckle ca7b7d3c99 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.
