media: docs: v4l2-controls: remove outdated paragraph

Browse Source 
This paragraph was added by commit a42b57f5aa ("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.

Finally, remove all control functions from your v4l2_ioctl_ops (if any):

vidioc_s_ctrl, vidioc_g_ext_ctrls, vidioc_try_ext_ctrls and vidioc_s_ext_ctrls.
Those are now no longer needed.
