We assumed that only a small set of compatiable strings would be needed to find the PCIe device tree nodes to be fixed up. However on newer platforms the simple rules no longer work. We need to allow specifying the PCIe compatiable string for each individual SoC. We introduce CONFIG_SYS_FSL_PCIE_COMPAT for this purpose and set it if the default isn't sufficient.
