x86: add apic probe for genapic 64bit, v2
introducing an APIC handling probing abstraction:
static struct genapic *apic_probe[] __initdata = {
&apic_x2apic_uv_x,
&apic_x2apic_phys,
&apic_x2apic_cluster,
&apic_physflat,
NULL,
};
This way we can remove UV, x2apic specific code from genapic_64.c and
move them to their specific genapic files.
[ v2: fix compiling when CONFIG_ACPI is not set ]
