Subject: [PATCH] csky: PCI: Define ARCH_GENERIC_PCI_MMAP_RESOURCE
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.
