[IA64] tree-wide: Misc __cpu{initdata, init, exit} annotations

* palinfo.c:

palinfo_cpu_notifier is a CPU hotplug notifier_block, and can be
marked __cpuinitdata, and the callback function palinfo_cpu_callback()
itself can be marked __cpuinit. create_palinfo_proc_entries() is only
called from __cpuinit callback or general __init code, therefore a
candidate for __cpuinit itself. remove_palinfo_proc_entries() is only
called from __cpuinit callback or general __exit code, therefore a
candidate for __cpuexit.

* salinfo.c:

The CPU hotplug notifier_block can be __cpuinitdata. The callback
salinfo_cpu_callback() is incorrectly marked __devinit -- it must
be __cpuinit instead.

* topology.c:

cache_sysfs_init() is only called at device_initcall() time so marking
it as __cpuinit is wrong and wasteful. It should be unconditionally
__init. Also cleanup reference to hotplug notifier callback function
from this function and replace with cache_add_dev(), which could also
enable us to use other tricks to replace __cpuinit{data} annotations,
as recently discussed on this list.

cache_shared_cpu_map_setup() is only ever called from __cpuinit-marked
functions hence both its definitions (SMP or !SMP) are candidates for
__cpuinit itself. Also all_cpu_cache_info can be __cpuinitdata because
only referenced from __cpuinit code.
