smdk4412-common: camera: fixes for camerawrapper

1. Enable ZSL Mode on both the cameras. Use Samsung Magic Command.
2. Remove workarounds that were meant for smdk4120. These are no
   longer required on smdk4412. Fixes ZSL and Face Detection.
3. Force release the camera when the preview is stopped to prevent
   issues with camera freezes that would require device reboots.
4. Disable Verbose logging to prevent spam during recording.
