Revert removal of power hint from PowerManager.aidl
Reverts all changes on PowerManagerService.cpp and bring back power hint
methods and usages.
This cl stops using the new PowerHalController, to confirm it is the cause
of the perf regression from b/157483189. Once confirmed it can be
reintroduced later once the root cause is fixed within the new code.
