media: Documentation: vivid.rst: drop "Video, VBI and RDS Looping"

Drop the "Video, VBI and RDS Looping" section, instead moving the
Video/VBI info to section "Video and Sliced VBI looping" and the
RDS info to section "Radio & RDS Looping".

-Video, VBI and RDS Looping
---------------------------
 
-The vivid driver supports looping of video output to video input, VBI output
-to VBI input and RDS output to RDS input. For video/VBI looping this emulates
-as if a cable was hooked up between the output and input connector. So video
-and VBI looping is only supported between S-Video and HDMI inputs and outputs.
-VBI is only valid for S-Video as it makes no sense for HDMI.
+Video and Sliced VBI Looping
+----------------------------
 
-Since radio is wireless this looping always happens if the radio receiver
-frequency is close to the radio transmitter frequency. In that case the radio
-transmitter will 'override' the emulated radio stations.

 The way to enable video/VBI looping is currently fairly crude. A 'Loop Video'
 control is available in the "Vivid" control class of the video
 capture and VBI capture devices. When checked the video looping will be enabled.

 stations at regular frequency intervals. Depending on the frequency of the
