Jack Ren ff9d667b49 Refine the BSP/AP boot flowchart to match BIOS boot flow ...

This is only for the debug purpose. It is still unclear whether it can work on
ICL.

WhiskyLake BIOS will start APs and then each AP will call mwait to wait for BSP to
write monitor memory location to wake them up. Currently the hypervisor
will send SIPI to each AP and re-initialize them after the hypervisor
boots up. So APs can't respond to the wakeup requests from BSP anymore.

Fix: the hypervisor should send SIPI to the APs only after BIOS wakes up the AP.
