dt-bindings: PCI: layerscape-pci: Replace fsl,lx2160a-pcie with fsl,lx2160ar2-pcie

The fsl,lx2160a-pcie compatible is used for mobivel according to the
Documentation/devicetree/bindings/pci/layerscape-pcie-gen4.txt file.

Whereas the fsl,layerscape-pcie is used for DesignWare PCIe controller binding.

So change it to fsl,lx2160ar2-pcie and allow a fall back to fsl,ls2088a-pcie.

While at it, sort compatible string.
