pci_decode: report devices from ACPI info

Browse Source 
Although we do not have the full ACPI information parsed yet, to
announce non-PCI devices derived from the ACPI tables, the device
description of the assumed devices is now integral-part of pci_decode.
Formerly, the information was gained separatedly as boot-module, whereby
we lost synchronization in between ACPI/PCI parsing, BIOS handover, and
PS/2 emulation code already acting.
