sched, sparc64: Turn cpu_coregroup_mask() into a real function

This compile error triggers on Sparc64:

   kernel/sched.c:7140: error: 'cpu_coregroup_mask' undeclared here (not in a function)

Because after the recent scheduler domain cleanups the scheduler
uses this arch method as a function pointer in a scheduler
topology data structure - which is not possible with a macro.
