drivers: camera: Move v4l2 subdev ops to tegracam

Move all v4l2 initialization to common framework, ensures
most of the duplicated code in sensor drivers reduced.
Now sensor drivers will have control and core ops for
all operations.

New ops - set_mode, start_streaming and stop_streaming
are added to modularize sensor drivers.

Update current sensor drivers with the new modifications.
