Add stub version of pci_device_map_memory_range

This stub version of pci_device_map_memory_range allows the vesa driver and
other users of this interface to continue functioning with current
libpciaccess bits.  That said, users of this interface should convert over
to pci_device_map_range as soon as possible.
