powerpc: Get merged kernel to compile and run on 32-bit SMP powermac.
This updates the powermac SMP code to use the mpic driver instead of
the openpic driver and fixes the SMP-dependent context switch code.
We had a subtle bug where we were using interrupt numbers 256-259 for
IPIs, but ppc32 had NR_IRQS = 256. Moved the IPIs down to use interrupt
numbers 252-255 instead.
