the softc is private to the device (it eventually copies informations
passed from the parent, and the attach informations could be properties
as well). up to now, device_properties() has been used to pass informations
which doesn't comes directly from the parent (as opposed to the attach
structure), and possibly from different place, and may possibly not be
there. If I understood it properly, we still want to have pchb to attach
at pci, but using informations from BIOS or ACPI if available.
It looks like this fits device_properties(), much more than and extention
of the pci attach args.
