These were incorrectly introduced and can cause problems for of_irq_init.

The correct way to define a root controller is no interrupt-parent set at
all or the interrupt-parent is set to the root controller itself when
inherited from a parent node.

Works for me. Now I can use my GPIO chained IRQs correctly.
