[CPUFREQ] unexport (un)lock_policy_rwsem* functions 



lock_policy_rwsem_* and unlock_policy_rwsem_* functions are scheduled
to be unexported when 2.6.33. Now there are no other callers of them
out of cpufreq.c, unexport them and make them static.

What:	lock_policy_rwsem_* and unlock_policy_rwsem_* will not be

	exported interface anymore.

When:	2.6.33

Why:	cpu_policy_rwsem has a new cleaner definition making it local to

	cpufreq core and contained inside cpufreq.c. Other dependent

	drivers should not use it in order to safely avoid lockdep issues.
