2015-04-02[media] add raw video stream support for Samsung SUR40Florian Echtler
This patch adds raw video support for the Samsung SUR40 using vbuf2-dma-sg. All tests from v4l2-compliance pass. Support for VB2_USERPTR is currently disabled due to unexpected interference with dma-sg buffer sizes.

We will never use packet_id before initializing it as we start with "need_blobs == -1" and will set packet_id there. Also use le32_to_cpu when fetching header->packet_id. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
