If we allow to attach pci at acpi, the information would come
directly from the parent. It is not only address space usage
but also interrupt routing and power management.

It would not be "the" pci attach args. That's the power of multiple
frontends that we can have special attach args, the softc extended
as needed and the extra code in its own source file which gets
only compiled if the kernel is configured that way.
With properties, you would have all that nasty parsing code in the
common sources. And no compile time type checks.
