Subject: [PATCH 1/1] dt-binding: memory-controllers: fsl,ifc: add compatible string fsl,ifc-nand

ifc can connect nor, nand and fpag. Add child node "nand@" under fsl,ifc
and compatible string "fsl,ifc-nand" when ifc connect to nand flash.

Fix below warning:
arch/arm64/boot/dts/freescale/fsl-ls1043a-qds.dtb: /soc/memory-controller@...0000/nand@1,0:
	failed to match any schema with compatible: ['fsl,ifc-nand']
