x86/apic: Replace io_apic_ops with x86_io_apic_ops.
Which makes the code fit within the rest of the x86_ops functions.
Acked-by: Suresh Siddha <suresh.b.siddha@intel.com>
[v1: Changed x86_apic -> x86_ioapic per Yinghai Lu <yinghai@kernel.org> suggestion]
[v2: Rebased on tip/x86/urgent and redid to match Ingo's syntax style]
