DTSes with new i.MX 8M SoCs introduce their own compatibles so add them
to fix dtbs_check warnings like:
arch/arm64/boot/dts/freescale/imx8mm-evk.dt.yaml: ddr-pmu@3d800000:
compatible:0: 'fsl,imx8mm-ddr-pmu' is not one of ['fsl,imx8-ddr-pmu', 'fsl,imx8m-ddr-pmu', 'fsl,imx8mp-ddr-pmu']
From schema: Documentation/devicetree/bindings/perf/fsl-imx-ddr.yaml
arch/arm64/boot/dts/freescale/imx8mm-evk.dt.yaml: ddr-pmu@3d800000:
compatible: ['fsl,imx8mm-ddr-pmu', 'fsl,imx8m-ddr-pmu'] is too long
arch/arm64/boot/dts/freescale/imx8mm-evk.dt.yaml: ddr-pmu@3d800000:
compatible: Additional items are not allowed ('fsl,imx8m-ddr-pmu' was unexpected)
