[media] media: fsl-viu: fix support for streaming with mmap method
Streaming using mmap didn't work in the VIU driver. We need to start/stop DMA in streamon/streamoff and free the buffers on release. Add appropriate driver extension now. Signed-off-by: Anatolij Gustschin <agust@denx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
