[CPUFREQ] Mark policy_rwsem as going static in cpufreq.c wont be exported 



lock_policy_rwsem_* and unlock_policy_rwsem_* routines in cpufreq.c are
currently exported to drivers. Improper use of those locks can
result in deadlocks and it is better to keep the locks localized.
Two previous in-kernel users of these interfaces (ondemand and conservative),
do not use this interfaces any more. Schedule them for removal.

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.
