To prepare for the task, users only need to enter the task.input, task.overlay(if need
combine) and task.output parameters, and then queue task either by
int
ipu_queue_task(struct ipu_task *task);
if from kernel level(v4l2 driver for example), or by
IPU_QUEUE_TASK ioctl under /dev/mxc_ipu if from application level.
