percpu: make percpu symbols in ia64 unique

This patch updates percpu related symbols in ia64 such that percpu
symbols are unique and don't clash with local symbols.  This serves
two purposes of decreasing the possibility of global percpu symbol
collision and allowing dropping per_cpu__ prefix from percpu symbols.

* arch/ia64/kernel/setup.c: s/cpu_info/ia64_cpu_info/

Partly based on Rusty Russell's "alloc_percpu: rename percpu vars
which cause name clashes" patch.
