Subject: [PATCH] x86: Move declaration for mp_register_ioapic()

Preparing patch for ioapic hotplug:
        PCI, x86, ACPI: Link acpi ioapic register to ioapic
as it adds calling in
        arch/x86/kernel/acpi/boot.c::acpi_register_ioapic()
                                     acpi_unregister_ioapic()

Address compiling problem when
 CONFIG_ACPI is defined
 CONFIG_X86_IOAPIC is not defined.

Change condition to X86_IO_APIC instead of ACPI.

-v2: update changelog requested by Bjorn.
