media: docs: move DVB audio/video docs to staging

The only upstream driver using the API described there is the
av7110 driver.

As the driver was moved to staging, move the API bits to staging
as well.

 The DVBv3 frontend API has issues with new delivery systems, including
 DVB-S2, DVB-T2, ISDB, etc.
 
-There's just one driver for a very legacy hardware using the Digital TV
-audio and video APIs. No modern drivers should use it. Instead, audio and
-video should be using the V4L2 and ALSA APIs, and the pipelines should
-be set via the Media Controller API.
