pci: layerscape: add official ls1028a binding support

The official bindind of the PCIe controller of the ls1028a has the
following compatible string:
  compatible = "fsl,ls1028a-pcie";

Additionally, the resource names and count are different. Update the
driver to support this binding and change the entry in the ls1028a
device tree.
