sparc64: Only allocate per-cpu areas for possible cpus.
This gets us real close to the generic implementation of
setup_per_cpu_areas() except:
1) We store the per-cpu offset into the trap_block[], whereas
the generic code has it's own static array.
2) We have to initialize the %g5 register to hold the boot cpu's
per-cpu area offset.
3) The OBP/MDESC cpu info scan is performed at the end.
