ata: libahci: Use of_platform_device_create only if supported
of_platform_device_create does not exist if OF_ADDRESS is not configured, so limit its use accordingly. Without this fix, the sparc64:allmodconfig build fails with ERROR: "of_platform_device_create" [drivers/ata/libahci_platform.ko] undefined!
