chs b0c781c459 apply the same change for powerpc as mrg did for arm and mips:
CPU_INFO_FOREACH() must always iterate at least the boot cpu.
document this in sys/cpu.h and fix the arm and mips versions
to check ncpu is non zero before using it as an iterator max.

this should fix the new assert in init_main.c.
