Add support to enable slice delivery mode feature. Driver will now be
getting one slice in each buffer. This mode is valid only for h264 and
when slicing is MB based. This will improve the performance in
streaming scenario as client can start streaming each slice instead
of waiting for the entire frame.

arguments specified by the V4L2 spec do not allow for flushing the input

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.

If V4L2_CAP_DEVICE_CAPS is set, then the new device_caps field is filled with
the capabilities of the opened device node.
The capabilities field traditionally contains the capabilities of the physical
device, being a superset of all capabilities available at the several device
nodes. E.g., if you open /dev/video0, then if it contains VBI caps then that means
that there is a corresponding vbi node as well. And the capabilities field of
both the video and vbi nodes should contain identical caps.
However, it would be very useful to also have a capabilities field that contains
just the caps for the currently open device, hence the new CAP bit and field.
