[PATCH 1/1] dt-bindings: PCI: layerscape-pci: Add deprecated property 'num-viewport'

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

Copy the 'num-viewport' property from snps,dw-pcie-common.yaml to
fsl,layerscape-pcie.yaml to address the below warning. This is necessary
due to historical reasons where fsl,layerscape-pcie.yaml does not
directly reference snps,dw-pcie-common.yaml.

/arch/arm64/boot/dts/freescale/fsl-ls1012a-frwy.dtb: pcie@3400000: Unevaluated properties are not allowed ('num-viewport' was unexpected)
