Name all ioctl references and make them match the ioctls that are documented. That will improve the cross-reference index, as it will have all ioctls and syscalls there. While here, improve the documentation, marking the deprecated ioctls, and making the non-deprecated ones more like the rest of the media book. Also, add a notice for ioctls that still require documentation. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

Description
|
|
===========
|
|
|
|
This ioctl is used to set the generation of a 22kHz tone burst for mini
|
|
DiSEqC satellite selection for 2x1 switches. This call requires
|
|
read/write permissions.
