sparc64: Fix UP bootup regression.
Commit b696fdc259f0d94348a9327bed352fac44d4883d ("sparc64: Defer cpu_data() setup until end of per-cpu data initialization.") broke bootup for UP builds because the cpu_data() initialization only occurs in setup_per_cpu_areas() which is never compiled in nor called in UP builds. Fix this up by calling the setups directly from init_64.c when non-SMP.
