The implementation of this new behavior aligns with the
guidelines outlined in the Intel SDM.

Following a power-up or RESET of an MP system, system hardware
dynamically selects one of the processors on the system bus as
the BSP. The remaining processors are designated as APs.
The APs complete a minimal self-configuration,
then wait for SIPI from the BSP processor

This series was reviewed by Ray before the soft freeze, it just lacked
a R-b from an OVMF maintainer (Jiewen or myself).

So unless anyone objects, I would like to merge this asap and include
it in the upcoming stable tag.
