[PATCH] ARM: sun7i: dt: Fix interrupt trigger types

[Maxime Ripard]

The Allwinner A20 uses the ARM GIC as its internal interrupts controller. The
GIC can work on several interrupt triggers, and the A20 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.

Fix this for the remaining DT nodes that slipped through.
