  'min_buffers_needed' is suppose to be used to indicate the number
of buffers needed by DMA engine to start streaming.
ipu3 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.
