PCI: layerscape: Fix assigning wrong address to LS2088A pcie cfg1 space

This bug is brought by the commit 3d8553f0a3 (pci: layerscape: add
LS2088A series SoC pcie support), which only updated cfg_res.start
and did not update the .end field. This causes fdt_resource_size()
getting wrong value when calculate the cfg1 space address.
