The i.MX 8M DTSes use two compatibles so update the binding to fix
dtbs_check warnings like:
arch/arm64/boot/dts/freescale/imx8mq-thor96.dt.yaml: interrupt-controller@32e2d000:
compatible: ['fsl,imx8m-irqsteer', 'fsl,imx-irqsteer'] is too long
From schema: Domentation/devicetree/bindings/interrupt-controller/fsl,irqsteer.yaml
arch/arm64/boot/dts/freescale/imx8mq-thor96.dt.yaml: interrupt-controller@32e2d000:
compatible: Additional items are not allowed ('fsl,imx-irqsteer' was unexpected)
