The EOI handler of MSI/MSI-X interrupts for P8 (PHB3) need additional
steps to handle the P/Q bits in IVE before EOIing the corresponding
interrupt. The patch changes the EOI handler to cover that.

The patch intends to initialize PHB3 during system boot stage. The
flag "PNV_PHB_MODEL_PHB3" is introduced to differentiate IODA2
compatible PHB3 from other types of PHBs.

The PHB3, which is compatible with IODA2, have lots of tables (RTT/
