In order to get any GPIO interrupts on my board, I needed to add the
summary IRQ first in this list. My reading of platform_get_irq is that
"interrupts-extended" is queried before "interrupts", so we
accidentally wire the summary IRQ to PDC 30. Given this, you can
probably remove the regular "interrupts" property.
