'min_buffers_needed' is suppose to be used to indicate the number
of buffers needed by DMA engine to start streaming.
imx7-media-csi driver doesn't use DMA engine and just want to specify
the minimum number of buffers to allocate when calling VIDIOC_REQBUFS.
That 'min_reqbufs_allocation' field purpose so use it.
