Impact: cleanup
cpu_coregroup_mask is the New Hotness.
As S/390 uses theirs internally, so we just make it static.

The default values for SD_MC_INIT cause an additional cpu usage of up
to 40% on some network benchmarks compared to the plain SD_CPU_INIT
values. So just define SD_MC_INIT to SD_CPU_INIT.
More tuning needs to be done.

Impact: New API
The old topology_core_siblings() and topology_thread_siblings() return
a cpumask_t; these new ones return a (const) struct cpumask *.

Like cpu_coregroup_map, but returns a (const) pointer.
Compile-tested on s390 (defconfig).
