An issue is seen on the BCM56060 SoC using the pinctrl-iproc-gpio.c driver
for one of its GPIO blocks.
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.
