In other places I've seen interrupts properties written as:
interrupts = < irq1... >,
< irq2... >,
< irqN... >;
Where each individual interrupt is surrounded by angle brackets. This produces
the exact same dtb, but may appear easier to read.
This might not be the right time and place to raise it, but it'd be nice if we
used one style consistently.
