[PATCH 4/4] ARM: dts: imx: Align GPMI NAND node name with schema

[Krzysztof Kozlowski]

Device tree schema expects NAND controller to be named
"nand-controller", otherwise dtbs_check complain with a warning like:

    arch/arm/boot/dts/imx6dl-apf6dev.dt.yaml: gpmi-nand at 112000:
        $nodename:0: 'gpmi-nand at 112000' does not match '^nand-controller(@.*)?'
