Log Message:

sparc64: use direct interrupt mapping for PCI devices
Every PCI Slot in PBM has 4 directly mapped IRQ lines.
Use the IRQ routing schema 0bssnn (Bus, Slot, interrupt Number)
described in Section 19.3.3 of UltraSPARC™-IIi User's Manual.
Please note that this patch requires the OpenBIOS counterpart patch.
