smdk4412-common:camera: workaround for snapshot crash with touch2focus and flash

Auto Exposure Lock is used during touch to focus
with flash enabled. This prevents the sensor for taking
a picture since the Lock is acquired but is not released.
Fixup the CameraParameters and prevent the Auto Exposure
Lock from being used."

overlay: camera: temporarily disable zsl mode to fix front camera

With the ZSL mode enabled, the front camera preview
is not restarted when a picture is taken, due to which
the preview is stuck and requires restarting the
camera. Temporarily disable ZSL until a proper fix is in place.
