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. Reviewed-by: Thierry Reding <treding@nvidia.com>

'#interrupt-cells' is not documented which causes a warning when 'unevaluatedProperties' is implemented. Unless the I2C controller is also an interrupt controller, '#interrupt-cells' is not valid. This doesn't appear to be the case from the driver, so just remove it from the example.
