arch: ia64: Remove CONFIG_OPROFILE support
The "oprofile" user-space tools don't use the kernel OPROFILE support
any more, and haven't in a long time. User-space has been converted to
the perf interfaces.
Also note that ia64 supports oprofile but not perf and profiling
shouldn't be working anyway currently.
Remove the old oprofile's architecture specific support.
