Interestingly I have a patch for this as well but it does the opposite and adds interrupt-controller and #interrupt-cells. Upon closer inspection I was tricked into this because the i2c-aspeed driver includes linux/irqchip/chained_irq.h and linux/irqdomain.h and therefore I assumed that it was indeed implementing an interrupt controller. But none of the symbols in those files are ever used, so your version seems to be correct.
