ANDROID: Sched: Add restricted vendor hook in schedule()

Browse Source 
This vendor hook is used to override the scheduler decisions
with our vendor scheduler logic

This vendor hook was part of
commit 292f430816
(ANDROID: Sched: Add restricted vendor hooks for scheduler)

But commit 7219ca326a
(Revert "ANDROID: Sched: Add restricted vendor hooks for scheduler")
deleted above vendor hooks stating unused

Adding back above vendor hooks required for EMS.
