x86: mp: Support APs waiting for instructions
At present the APs (non-boot CPUs) are inited once and then parked ready
for the OS to use them. However in some cases we want to send new requests
through, such as to change MTRRs and keep them consistent across CPUs.
Change the last state of the flight plan to go into a wait loop, accepting
instructions from the main CPU.
Drop cpu_map since it is not used.
