I'm not sure if any additional SoC support is actually needed. 'fsl,imx-
irqsteer' is available and that's what I use in my WiP. Also imx8mp also just 
uses the generic compatible. Only imx8mq uses 'fsl,imx8m-irqsteer'.
AFAICS the bindings support the different amount of IRQs already.

Best regards,
Alexander
