[PATCH 1/1] pinctrl: iproc: Set irq handler based on trig type

[Hamish Martin <hamish.martin@xxxxxxxxxxxxxxxxxxx>]

Rather than always using handle_simple_irq() as the gpio_irq_chip
handler, set a more appropriate handler based on the IRQ trigger type
requested.
This is important for level triggered interrupts which need to be
masked during handling.
