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:

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.

848d10314b [media] fix broken references on dvb/video*rst
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.
