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

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

This vendor hook was part of
commit 292f4308
(ANDROID: Sched: Add restricted vendor hooks for scheduler)

But commit 7219ca32
(Revert "ANDROID: Sched: Add restricted vendor hooks for scheduler")
deleted above vendor hooks stating unused

Adding back above vendor hooks required for EMS.
