[media] v4l: removal of old, obsolete ioctls
Some ioctl's were defined wrong on 2.6.2 and 2.6.6, using the wrong
type of R/W arguments. They were fixed, but the old ioctl names are
still there, maintained to avoid breaking binary compatibility:
There's no sense on preserving those forever, as it is very doubtful
that someone would try to use a such old binary with a modern kernel.
Removing them will allow us to remove some magic done at the V4L ioctl
handler.
Note that any application compiled with a videodev2.h from 2.6.7 or later
will be using the correct ioctls.
