Igor Mammedov 53a89e262b target-i386: Move APIC to ICC bus 
It allows APIC to be hotplugged.

 * map APIC's mmio at board level if it is present
 * do not register mmio region for each APIC, since
   only one is used/mapped

Igor Mammedov f0513d2c01 target-i386: Introduce ICC bus/device/bridge 
Provides a hotpluggable bus for APIC and CPU.

* icc-bridge will serve as a parent for icc-bus and provide
  mmio mapping services to child icc-devices.
* icc-device will replace SysBusDevice as a parent of APIC
  and IOAPIC devices.
