Strictly speaking, a node's default interrupt-parent is its physical
parent. And a node without interrupt-map identity maps all interrupts
to *its* parent. So the interrupt is notionally wired from the child
to its parent and so forth up the bus tree until it reaches a node
with a specified interrupt-parent or interrupt-map.
