Remove unnecessary onDeveloperOptionsSwitchEnabled/Disabled override.

- default implementation has been added in the super class to handle
enabling/disabling the preference when the master developer options
switch it turned on/off. Removing all subclass that originally
implemented the methods that only contains the default behavior.
