Adapt to new controls (subsampling).
For encoding, the destination format now needs to be set to V4L2_PIX_FMT_JPEG
and the subsampling (4:2:2 or 4:2:0) needs to be set using the respective
control (V4L2_CID_JPEG_CHROMA_SUBSAMPLING). Required buffer size for
destination image during encoding is no longer deduced from the format (which
generally implied overestimation), but needs to be given from userspace in
sizeimage.
Not strictly related to the added controls, this patch also fixes setting the
subsampling of the destination image for decoding, depending on the destination
format.

of undoing actions taken in the probe callback() and freeing resources
on driver detach. This eliminates the need for manually releasing

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.

The V4L2_CID_JPEG_CLASS control class is intended to expose various
adjustable parameters of JPEG encoders and decoders. Following controls
are defined:
- V4L2_CID_JPEG_CHROMA_SUBSAMPLING,
- V4L2_CID_JPEG_RESTART_INTERVAL,
- V4L2_CID_JPEG_COMPRESSION_QUALITY,
- V4L2_CID_JPEG_ACTIVE_MARKER.
This covers only a part of relevant standard specifications. More
controls should be added in future if required.
The purpose of V4L2_CID_JPEG_CLASS class is also to replace some
functionality covered by VIDIOC_S/G_JPEGCOMP ioctls, i.e. the JPEG
markers presence and compression quality control. The applications
and drivers should switch from the ioctl to control based API, as
described in the subsequent patches for the Media API DocBook.

i.MX2x SoCs have a PrP which is capable of resizing and format
conversion of video frames. This driver provides support for
resizing and format conversion from YUYV to YUV420.
This operation is of the utmost importance since some of these

accepts YUV420 as input.

Correctly sets the max/min/default values for the hdpvr picture
controls. The reason the current values didn't cause a problem until now
is because any firmware <= 0.15 didn't support them. The latest firmware
releases properly support picture controls and the values in the patch
are derived from the windows driver using SniffUSB2.0.
