cpu/apic: drop icc bus/bridge
After CPU hotplug has been converted to BUS-less hot-plug infrastructure, the only function ICC bus performs is to propagate reset to LAPICs. However LAPIC could be reset by registering its reset handler after all device are initialized. Do so and drop ~30LOC of not needed anymore ICCBus related code.
