V4L2_CID_MPEG_STREAM_VBI_FMT controls if and how VBI data is embedded in
an MPEG stream. Currently only one format is supported: the format designed
for the ivtv driver. This should be extended with new standard formats
(such as defined for DVB) in the future.

CX2341X port was always set to 'memory', but 'streaming' is also possible

ivtv uses the memory (DMA) interface with the CX2341X, while pvrusb2 and
cx88-blackbird use the streaming interface. This setting is now selectable
by the driver.
