drivers/intel/fsp2_0: Perform MP init post FSP-MultiPhase SI Init
FSP can also make use of Multi-Processor services during its
multi-phase stages. If `USE_INTEL_FSP_MP_INIT' is set and
`USE_INTEL_FSP_TO_CALL_COREBOOT_PUBLISH_MP_PPI' unset coreboot cannot
take MP ownership as FSP-S may still use EDK2 MP services
concurrently.
TEST=verified on Lunar Lake RVP board (lnlrvp)
