I do not now if the patch is working oe not but to reduce the #if forrest

#ifndef __aarch64_
          if (pci_device_is_boot_vga(info))
#endif
          {
		primaryBus.type = BUS_PLATFORM;
		primaryBus.id.plat = pd;
 	  }


more over i would change the architecture depending part into something
more functional like IGNORE_BOOT_VGA


note i am not the maintainer, just my 2 cents
