ARM: sun6i: dt: Fix interrupt trigger types
The Allwinner A31 uses the ARM GIC as its internal interrupts controller. The
GIC can work on several interrupt triggers, and the A31 was actually setting it
up to use a rising edge as a trigger, while it was actually a level high
trigger, leading to some interrupts that would be completely ignored if the
edge was missed.
