V4L/DVB (4202): allow selecting CX2341x port mode
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. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
