[PATCH v3 1/1] dt-bindings: PCI: layerscape-pci: Fix property 'fsl,pcie-scfg' type

[Frank Li <Frank.Li@nxp.com>]

fsl,pcie-scfg actually need an argument when there are more than one PCIe
instances. Change it to phandle-array and use items to describe each field
means.

Fix below warning.

arch/arm64/boot/dts/freescale/fsl-ls1043a-rdb.dtb: pcie@3400000: fsl,pcie-scfg:0: [22, 0] is too long
        from schema $id: http://devicetree.org/schemas/pci/fsl,layerscape-pcie.yaml#

Change form v2 to v3
