common/simple_spin: use __ppc_yield() on all powerpc archs

__ppc_yield() is declared in sys/platform/ppc.h by glibc, for better
portability we just use the inlined assembly here. the shared resource
hints are supported by PowerPC ISA 2.06 but on older PowerPC cores, they
are no-ops. so it's fine to do this way.
