csky: PCI: Define ARCH_GENERIC_PCI_MMAP_RESOURCE

stffrdhrn · bjorn-helgaas · commit f619d23576f7 · 2022-07-22T17:26:10.000-05:00
This looks to be something that was accidentally left out on the csky port. Define ARCH_GENERIC_PCI_MMAP_RESOURCE to keep it inline with other ports. Adding ARCH_GENERIC_PCI_MMAP_RESOURCE enables the definition of modern pci_mmap_resource_range() functions which is generally what new ports should be using.
