powerpc: convert to generic helpers for IPI function calls
This converts ppc to use the new helpers for smp_call_function() and
friends, and adds support for smp_call_function_single().
ppc loses the timeout functionality of smp_call_function_mask() with
this change, as the generic code does not provide that.
