This computation looks wrong: the "interrupts" property refers to interrupts
that are referenced by this node and provided by an interrupt-controller,
while the "#interrupt-cells" property refers to interrupts provided by
this node. They don't need to have any relation.
We will use of_irq_count instead.
Thanks
