From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Move definitions of symbols related to transition latency and
sampling rate to include/linux/cpufreq.h so they can be used by
(future) goverernors located outside of drivers/cpufreq/.

No functional changes.

This patch was new in v4, no changes since then.
