When a GPIO on this block is used as a level sensitive interrupt the downstream handler is not invoked until the level returns to its previous (non-interrupting) state. This makes the level sensitive interrupts unusable. Edge sensitive interrupts are not affected. The fix is to simply ensure that we use a more appropriate handler (handle_level_irq) for the interrupt based on what trigger type has been configured. Similar setting of the handler is done in numerous other drivers.
