[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.

but the old version has been kept around for easier testing. Note this
doesn't impact the old P5 and WinChip machine check handlers.

----------------------------
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.
