android_rvh_sched_nohz_balancer_kick hook allows vendor modules to
select the busiest CPU in a group during load balance. When the
load balancer could not pull tasks from this busiest CPU due to
affinity restriction, the CPU is cleared from env->cpu. This must
be passed to the vendor module, otherwise we keep selecting the
exempted CPU as the busiest CPU.

The following restrict vendor hooks are added. The vendor hook
can selectively opt in for the default scheduler behavior by not
modifying the done argument.
- android_rvh_sched_newidle_balance: For newly idle load balance.
- android_rvh_sched_nohz_balancer_kick: For deciding if an idle
CPU is woken up to do nohz balance or not.
- android_rvh_find_busiest_queue: For selecting the busiest runqueue
among the CPUs in the busiest group selected in find_busiest_group.
- android_rvh_migrate_queued_task: Vendor implementations may require
both source and destination CPUs runqueue locks to be held while
calling set_task_cpu() during a task migration. Add a hook when
a queued task is migration so that vendor implementation can detach
the task and call set_task_cpu() with both runqueue locks held.
