This patch adds definition of the Samsung S5C73M3 camera specific
image format. V4L2_PIX_FMT_S5C_UYVY_JPG is a two-planar format,
the  first plane contains interleaved UYVY and JPEG data followed
by meta-data. The second plane contains additional meta-data needed
for extracting JPEG and UYVY data stream from the first plane.

This patch adds media bus pixel code for the interleaved JPEG/UYVY
image format used by S5C73MX Samsung cameras. This interleaved image
data is transferred on MIPI-CSI2 bus as User Defined Byte-based Data.
It also defines an experimental vendor and device specific media bus
formats section and adds related DocBook documentation.

changeset 1248c7cb broke html compilation:

Documentation/DocBook/media_api.xml:74: parser error : Failure to process entity sub-v4l2
Documentation/DocBook/media_api.xml:74: parser error : Entity 'sub-v4l2' not defined

I suspect that one file was simply missed at the patch. Yet, keeping
it broken is a very bad idea, so we should either remove the broken
patch or to remove just the invalid include. Let's take the latter
approach.

Due to that, a warning is now produced:

Old EOPNOTSUPP & ENOSYS could be still returned by some drivers
as well as other "non standard" error codes.

EAGAIN is returned in case of device is in state where it cannot
perform requested operation. This is for example sleep and statistics
are queried. Quick check for few demodulator drivers reveals there is
a lot of different error codes used in such case currently, few to
mention still: EOPNOTSUPP, ENOSYS, EAGAIN ... Lets try harmonize.
