[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.
