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.
