Fix shifting problem in location services page

Browse Source 
Controller generates the injection location settings
in updateState() which happens in onResume.
That's the primary reason why we observed the shifting issue.

In a good practice, we generate preference in displayPreference(),
and then update the setting state in updateState().

In this cl, we create a base controller class to encapsulate
most implementation, and developer need to inject location
services in child class.

Test: Add work profile, and see correct services list.
