71533c8a83 ACPI - fixed initialization of pci briges irqtable
- if no IRQ table is found, we report that ACPI cannot map IRQ
  correctly

- fixes mapping of IRQs in KVM because in this case we just fall
  through and use the IRQ configured by BIOS. PCI still reports
  that it failed to use ACPI. It is a hint if things go wrong.

40bfed28cd ACPI pci-to-pci bridges
- every pci device which implements _PRT acpi method is considered to
  be a pci-to-pci bridge

- acpi driver constructs a hierarchy of pci-to-pci bridges

- when pci driver identifies a pci-to-pci bridge it tells acpi driver
  what is the primary and the secondary bus for this device

- when pci requests IRQ routing information from acpi, it passes the
  bus number too to be able to identify the device accurately
