PNPACPI sets pnpdev->dev.archdata
Teach PNPACPI how to hook up its devices to their ACPI nodes, so that pnpdev->dev.archdata points to the parallel acpi device node. Previously this only worked for PCI, leaving a notable hole. Export "acpi_bus_type" so this can work. Remove some extraneous whitespace.
