[media] s5p-jpeg: Add JPEG controls support
This patch replaces VIDIOC_S/G_JPEGCOMP ioctl handlers with
V4L2_CID_JPEG_QUALITY control. Additionally it enables JPEG subsampling
and the restart interval configuration through V4L2_CID_JPEG_SUBSAMPLING
and V4L2_CID_JPEG_RESTART_INTERVAL controls. For the decoder video node
only V4L2_CID_JPEG_SUBSAMPLING is available as a read-only control.

[media] Exynos4 JPEG codec v4l2 driver
Add driver for the JPEG codec IP block available in Samsung Exynos SoC series.
The driver is implemented as a V4L2 mem-to-mem device. It exposes two video
nodes to user space, one for the encoding part, and one for the decoding part.
