This looks to be something that was left out on accident on the csky port. Add the definition of ARCH_GENERIC_PCI_MMAP_RESOURCE to keep it inline with other ports. Adding ARCH_GENERIC_PCI_MMAP_RESOURCE enables the definition of mordern pci_mmap_resource_range functions which is generally what new ports should be using.
