rG7ed09a6778d3: powerpc: Rework IPI message processing
Summary

There's no need to use a while loop in the IPI handler, the message list
is cached once and processed. Instead, since the existing code calls
ffs(), sort the handlers, and use a simple 'if' sequence.

Test Plan

Boot a SMP PowerPC system
