Subject: [PATCH 22/22] arm64: dts: imx8mp: Remove i.MX7 compatible from DDR PMU

The DDR PMU on i.MX 8MP has its own compatible described in bindings and
used in the driver (with its own quirks).  Remove additional
fsl,imx8m-ddr-pmu compatible to fix dtbs_check warnings like:

  arch/arm64/boot/dts/freescale/imx8mq-nitrogen.dt.yaml: ddr-pmu@...00000:
    compatible: ['fsl,imx8mq-ddr-pmu', 'fsl,imx8m-ddr-pmu'] is not valid under any of the given schemas (Possible causes of the failure):
    arch/arm64/boot/dts/freescale/imx8mq-nitrogen.dt.yaml: ddr-pmu@...00000: compatible: ['fsl,imx8mq-ddr-pmu', 'fsl,imx8m-ddr-pmu'] is too long
    From schema: Docmentation/devicetree/bindings/perf/fsl-imx-ddr.yaml
