Patchset:

PS13: 
Ack on the pre-FSP platforms and FSP platforms
with neither USE_INTEL_FSP_MP_INIT nor
USE_INTEL_FSP_TO_CALL_COREBOOT_PUBLISH_MP_PPI.
The rest seems hidden in a mist.

Subrata, Nate, where is the sequence documented for platforms without
`SkipMpInit` but with `CpuMpPpi`? How can we know when things are done?
