Log Message:
powerpc: count intr events on the correct cpu

The powerpc pic code doesn't support routing but an interrupt may fire
elsewhere (think IPIs). Instead of always reporting events on CPU 0,
record the last CPU index to handle the interrupt in struct intrsource
and use that when reporting affinity / event counters.

nintendo$ intrctl list
