Introduce a new structure CPUS as the controller of ICC (INTERRUPT
CONTROLLER COMMUNICATIONS), and new bus "ICC" to hold APIC,instead
of sysbus. So we can support APIC hot-plug feature.

When I tried to enable cpu hotplug feature for qemu-kvm, I found that the ACPI
device eject event just skipped by kernel.

A bunch of patches, which are applied separately for kernel and qemu-kvm,
and make x86 based linux guest with cpu hotplug feature.
For kernel:

--call acpi eject event handler in acpi_bus_notify()
For qemu-kvm:

Separate apic from qbus to icc bus which supports hotplug feature.
And make the creation of apic as part of cpu initialization, so
apic's state has been ready, before setting kvm_apic.
