The ep node device tree name is governed by these bindings: https://github.com/torvalds/linux/blob/master/Documentation/ devicetree/bindings/pci/layerscape-pci.txt#L24
As per above the ep compatible node contains platform name. Therefore, define the ep node compatible as CONFIG to find the pcie ep node in device tree during device tree fixup.
