decompress NV12 UBWC VisionBuf to NV12 with sde rotator hardware. This uses v4l2 to set the input frame buffer format (in this case, V4L2_PIX_FMT_NV12_UBWC) to the desired format (decompressed V4L2_PIX_FMT_NV12). A program will provide put_frame(vision_buf), with a pointer to an allocated visionbuf which needs to be decompressed which will then send the command to the hardware. Then call get_frame which will poll the rotator fd and return a pointer to the decompressed vision buffer.
Note that OUTPUT buffers are the inputs (nv12_ubwc) and CAPTURE buffers are the output (nv12).
