The 10-bit packed raw bayer format documented that the data of the first
pixel of a four-pixel group was found in the first byte and the two
highest bits of the fifth byte. This was not entirely correct. The two
bits in the fifth byte are the two lowest bits. The second pixel occupies
the second byte and third and fourth least significant bits and so on.

Fix those warnings:
Documentation/media/uapi/cec/cec-ioc-dqevent.rst:124: WARNING: c:func reference target not found: clock_gettime(2)
By replacing it with the right function name, using this shell script:
for i in `find Documentation/media -type f`; do sed 's,clock_gettime(2),clock_gettime,' <$i >a && mv a $i; done
Please notice that this will make the nitpick mode to shut up
complaining about that, becasue clock_gettime is on its exclude list,
but the cross reference will be undefined until someone documents
this function at the core documentation.

Trivially fix those broken references, by copying the structs
fron the header, just like other API documentation at the
DVB side.
This doesn't have the level of quality used at the V4L2 side
of the API, but, as this documents a deprecated API, used
only by av7110 driver, it doesn't make much sense to invest
time making it better.

instead of declaring the uAPI structs using usual refs, e. g.:
.. _foo-struct:
Use the C domain way:
.. c:type:: foo_struct
This way, the kAPI documentation can use cross-references to
point to the uAPI symbols.
That solves about ~100 undefined warnings like:
