Subject: [PATCH 3/3] ARM: dts: imx: move NAND properties under nand@0 node
Move NAND flash properties under the nand@0 node and place partition
properties under the partitions node.
Fix below CHECK_DTBS warnings:
arch/arm/boot/dts/nxp/imx/imx27-apf27.dtb: nand-controller@...00000 (fsl,imx27-nand): Unevaluated properties are not allowed ('#address-cells', '#size-cells', 'clocks', 'nand-bus-width', 'nand-ecc-mode', 'nand-on-flash-bbt', 'partition@0', 'partition@...000', 'partition@...000', 'partition@...000', 'partition@...000', 'partition@...000', 'partition@...000' were unexpected)
from schema $id: http://devicetree.org/schemas/mtd/mxc-nand.yaml
