x86: intel_cacheinfo misc section annotation fixes

cache_shared_cpu_map_setup() and cache_remove_shared_cpu_map()
are functions called from another function that is __cpuinit.  But the
!CONFIG_SMP empty-body stubs of these functions are unconditionally
marked __init, which is actively wrong, and will lead to oops.  But we
never saw this oops, because they always managed to get inlined in their
callsites, by virtue of being empty-body stubs!  They should still be
__cpuinit, of course.

assocs[], levels[] and types[] are only referenced from function that is
__cpuinit.  So these are candidates for being marked __cpuinitdata.
