Hans Verkuil a10b215325 media: vb2: add (un)prepare_streaming queue ops 
When userspace called VIDIOC_STREAMON, then you want to claim any streaming
resources needed and validate the video pipeline. Waiting for
start_streaming to be called is too late, since that can be postponed
until the required minimum of buffers is queued.

So add a prepare_streaming op (optional) that can be used for that
purpose, and a matching unprepare_streaming op (optional) that can
release any claimed resources. The unprepare_streaming op is called
when VIDIOC_STREAMOFF is called and q->streaming is 1, or when the
filehandle is closed while q->streaming is 1.
