cpumask: Introduce cpumask_of_{node,pcibus} to replace {node,pcibus}_to_cpumask

Browse Source 
Impact: New APIs

The old node_to_cpumask/node_to_pcibus returned a cpumask_t: these
return a pointer to a struct cpumask.  Part of removing cpumasks from
the stack.

This defines them in the generic non-NUMA case.
