Subject: [PATCH 0/3] ARM: dts: imx: cleanup most gpmi related CHECK_DTB
 warning

Only few warning left because original data is wrong
arch/arm/boot/dts/nxp/imx/imx6ull-engicam-microgea-bmm.dtb: nand-controller@...6000 (fsl,imx6q-gpmi-nand): nand@0:nand-ecc-step-size: 0 is less than the minimum of 1

driver will leave default value when these value is 0, but binding require
start from 1.

Since 2019 year, commit
        (212e496935929 dt-bindings: mtd: Add YAML schemas for the generic NAND options)
        NAND related property is preferred located under nand@<n> even though only
        one NAND chip supported.

NAND related property should be located under nand@0. This format already
support quite long time, so it should be safe to switch to modern format.
