Memory and CPU hot unplug are both asynchronize procedures.
When the unplug operation happens, unplug request cb is called first.
And when ghest OS finished handling unplug, unplug cb will be called
to do the real removal of device.
This patch adds hotunplug cb for pc machine, and memory and CPU
hot unplug will base on it.
