powerpc/pci: Use generic pci_mmap_resource_range()
Commit f719582435 ("PCI: Add pci_mmap_resource_range() and use it for
ARM64") added this generic function with the intent of using it everywhere
and ultimately killing the old arch-specific implementations.
Remove the powerpc-specific pci_mmap_page_range() and use the generic
pci_mmap_resource_range() instead.
Powerpc can mmap I/O port space, so supply the powerpc-specific
pci_iobar_pfn() required to make that work.
