Pawel Osciak bd60ad374e CHROMIUM: vb2: Add a new "use_dma_bidirectional" queue flag. 
When set to 1 for CAPTURE queues by the driver on calling vb2_queue_init(),
forces the buffers on the queue to be allocated/mapped with
DMA_BIDIRECTIONAL DMA direction flag, instead of DMA_FROM_DEVICE. This
allows the device not only to write to the buffers, but also read out from
them. This may be useful e.g. for codec hardware, which may be using
CAPTURE buffers as reference to decode other buffers.

This flag is ignored for OUTPUT queues, as we don't want to allow HW to
be able to write to OUTPUT buffers.
