 * @param[in]   and_mask Binary or of enum ia_css_event_irq_mask_type. An event
                        IRQ for the Host is only raised after all pipe related
                        events have occurred at least once for all the active
                        pipes. Events are remembered and don't need to occure
                        at the same moment in time. There is no control over
                        the order of these events. Once an IRQ has been raised
                        all remembered events are reset.
 * @return              IA_CSS_SUCCESS.
 *
 Controls when the Event generator in the CSS raises an IRQ to the Host.
 The main purpose of this function is to reduce the amount of interrupts
 between the CSS and the Host. This will help saving power as it wakes up the
 Host less often. In case both or_mask and and_mask are
 IA_CSS_EVENT_TYPE_NONE for all pipes, no event IRQ's will be raised. An
 exception holds for IA_CSS_EVENT_TYPE_PORT_EOF, for this event an IRQ is always
 raised.
 Note that events are still queued and the Host can poll for them. The
 or_mask and and_mask may be be active at the same time\n
 \n
 Default values, for all pipe id's, after ia_css_init:\n
 or_mask = IA_CSS_EVENT_TYPE_ALL\n
 and_mask = IA_CSS_EVENT_TYPE_NONE\n
 \n
 Examples\n
 \code
 ia_css_pipe_set_irq_mask(h_pipe,
 IA_CSS_EVENT_TYPE_3A_STATISTICS_DONE |
 IA_CSS_EVENT_TYPE_DIS_STATISTICS_DONE ,
 IA_CSS_EVENT_TYPE_NONE);
 \endcode
 The event generator will only raise an interrupt to the Host when there are
 3A or DIS statistics available from the preview pipe. It will not generate
 an interrupt for any other event of the preview pipe e.g when there is an
 output frame available.

 \code
 ia_css_pipe_set_irq_mask(h_pipe_preview,
        IA_CSS_EVENT_TYPE_NONE,
        IA_CSS_EVENT_TYPE_OUTPUT_FRAME_DONE |
        IA_CSS_EVENT_TYPE_3A_STATISTICS_DONE );

 ia_css_pipe_set_irq_mask(h_pipe_capture,
        IA_CSS_EVENT_TYPE_NONE,
        IA_CSS_EVENT_TYPE_OUTPUT_FRAME_DONE );
 \endcode
 The event generator will only raise an interrupt to the Host when there is
 both a frame done and 3A event available from the preview pipe AND when there
 is a frame done available from the capture pipe. Note that these events
 may occur at different moments in time. Also the order of the events is not
 relevant.

 \code
 ia_css_pipe_set_irq_mask(h_pipe_preview,
        IA_CSS_EVENT_TYPE_OUTPUT_FRAME_DONE,
        IA_CSS_EVENT_TYPE_ALL );

 ia_css_pipe_set_irq_mask(h_pipe_capture,
        IA_CSS_EVENT_TYPE_OUTPUT_FRAME_DONE,
        IA_CSS_EVENT_TYPE_ALL );
 \endcode
 The event generator will only raise an interrupt to the Host when there is an
 output frame from the preview pipe OR an output frame from the capture pipe.
 All other events (3A, VF output, pipeline done) will not raise an interrupt
 to the Host. These events are not lost but always stored in the event queue.
