v2: remove the subject prefix "LF-2571-1"
v3: put it into Documentation/devicetree/bindings/arm/fsl.yaml
    modify the description of nvmem-cells
    use "make ARCH=arm64 dtbs_check" to test it and fix errors
v4: use allOf to limit new version DTS files for i.MX8M to include
    "fsl,imx8mm/n/p/q-soc", nvmem-cells and nvmem-cells-names
v5: correct the error of using allOf
