ANDROID: cpufreq: Add a restricted vendor hook for freq transition

Browse Source 
A restricted vendor hook for cpufreq transition. The hook is
invoked per policy after changing the policy->cur and passes
policy as an argument.

This reverts commit 171ace325c which is a
revert of the original change. Hence, this brings back the original
change.
