media: docs: v4l2-controls: remove outdated paragraph
This paragraph was added by commit a42b57f5aacf ("V4L/DVB: Documentation: add v4l2-controls.txt documenting the new controls API") back in 2010, when the controls API has been improved. Nowadays it is a bit anachronistic, so remove it. The same information is stated in up-to-date wording a few paragraphs later > You’re done! And this is sufficient for most of the drivers we have. No > need to do any validation of control values, or implement QUERYCTRL, > QUERY_EXT_CTRL and QUERYMENU. And G/S_CTRL as well as G/TRY/S_EXT_CTRLS > are automatically supported.
