PATCH 1/1 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.
