Subject: [PATCH v2 5/10] cpufreq: Move governor attribute set headers to cpufreq.h

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

Move definitions and function headers related to struct gov_attr_set
to include/linux/cpufreq.h so they can be used by (future) goverernors
located outside of drivers/cpufreq/.

No functional changes.

Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

New patch.  Needed to move cpufreq_schedutil.c to kernel/sched/.
