smdk4412-common: camera: fix EXIF attributes for S5C73M3 sensor

S5C73M3 sensor which is the back camera, doesn't return the EXIF
attributes using V4L2 IOCTL. This sensor interleaves YUV and JPEG
frames along with Metadata which contains the EXIF information.

This patch does the following:
Manually extract the EXIF information from the interleaved metadata
and implement ISO, Flash, Exposure, Exposure Time and Exposure Bias
EXIF attributes for S5C73M3.
Fix incorrect Exposure EXIF attribute that was reporting as 1'.

smdk4412-common: camera: fix scene mode snapshot capture crashes

Few Scene Modes (like Night, High Sensitivity) if set as default,
after the camera opens, require the scene mode to be set when the
stream is turned on inorder to properly take effect. Not doing so
will result in crashes while trying to capture the snapshot.

smdk4412-common: camera: reorganize camera parameters

Few Scene modes require Flash and few don't. However all of
the scene modes require the focus to be AUTO. Reorganize the
camera parameters to set the Flash and Focus modes based on
the scene mode.

Changes adapted from Exynos5 Camera HAL.

smdk4412-common: camera: several fixes for autofocus

Setting the AutoFocus off using V4L2_CID_CAMERA_SET_AUTO_FOCUS will
reset the AF position of the sensor and this was done whenever
autofocus was completed. This totally defeated the purpose of touch
to focus since the sensor AF position was being reset after focus
and had to be refocussed while taking the snapshot. This also led to
several issues with third party applications since this kind of focus
behaviour was not intended.

S5C73M3 Back camera Interleaves YUV and JPEG along with metadata. This
metadata contains the AutoFocus result. Hence we could parse the
autofocus result instead of using V4L2 IOCTL, which is more efficient.
Also, the sensor exhibits issues when AutoExposure and AutoWhite Balance
locks are used with Flash ON. Improper locking could lead to freezing of
the sensor while taking a snapshot. Hence, only lock AEAWB when flash is
OFF and unlock them after AutoFocus finishes.

smdk4412-common: camera: enable ZSL mode on front camera

We are querying FIMC2 for the capture output and hence we
have no reason to restart the preview to have the preview
resolution match the capture resolution, which is not how
Zero Shutter Lag works. We could have different resolutions
for the preview and capture, hence don't stop the preview
for resizing.
