Log Message:
powerpc: Don't enable interrupts before calling cascaded intr handler.

Before calling a normal interrupt handler, the pic code adjusts cpl and
enables interrupts. Don't do this with interrupt sources that feed
cascaded pics as the resulting handler will do it anyway, and it can
result in multiple interrupts firing on the parent pic just to service
a single interrupt on the child.
