Subject: [PATCH] mfd: arizona: Try to use interrupt flags from interrupt
 controller

If no irq_flags are passed in platform data then query the interrupt
controller for the trigger type and try to use that. This provides
default operation with a wider range of hardware and will be needed
for device tree support where the interrupt flags are configured on
the interrupt controller.
