According to current semantics of power monitor, this commit adds a callback function to decide whether aborts the sleep by checking current value against the expected value and vhost_get_monitor_addr to provide address to monitor. When no packet come in, the value of address will not be changed and the running core will sleep. Once packets arrive, the value of address will be changed and the running core will wakeup.
