cpufreq: Move governor attribute set headers to cpufreq.h
Browse files Browse the repository at this point in the history
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.
