sparc64: fix pci_iounmap() when CONFIG_PCI is not set
Guenter reported [1] that the pci_iounmap() changes remain problematic, with sparc64 allnoconfig and tinyconfig still not building due to the header file changes and confusion with the arch-specific pci_iounmap() implementation. I'm pretty convinced that sparc should just use GENERIC_IOMAP instead of doing its own thing, since it turns out that the sparc64 version of pci_iounmap() is somewhat buggy (see [2]). But in the meantime, this just fixes the build by avoiding the trivial re-definition of the empty case.
