percpu: fix build breakage on s390 and cleanup build configuration tests
Commit bbddff05 (percpu: use percpu allocator on UP too) incorrectly excluded pcpu_build_alloc_info() on SMP configurations which use generic setup_per_cpu_area() like s390. The config ifdefs are becoming confusing. Fix and clean it up by, * Move pcpu_build_alloc_info() right on top of its two users - pcpu_{embed|page}_first_chunk() which are already in CONFIG_SMP block. * Define BUILD_{EMBED|PAGE}_FIRST_CHUNK which indicate whether each first chunk function needs to be included and use them to control inclusion of the three functions to reduce confusion.
