2021-02-17soc/intel/xeon_sp/smmrelocate: Don't run twice on the BSPArthur Heymans
This only makes sense if relocation via MSR is possible, to relocate APs in parallel. xeon_sp hardware does not support these MSR. TESTED: ocp/deltalake boots fine. SMM is relocated on CPU 0 just like all other cores.

2020-11-24soc/intel/xeon_sp: Enable SMI handlerRocky Phagura
SMI handler was not installed for Xeon_sp platforms. This enables SMM relocation and SMI handling. TESTED: - SMRR are correctly set - The save state revision is correct (0x00030101) - SMI's are properly generated and handled - SMM MSR save state are not supported, so relocate SMM on all cores in series - Verified on OCP/Deltalake mainboard. NOTE: - Code for accessing a CPU save state is not working for SMMLOADERV2, so some SMM features like GSMI, SMMSTORE, updating the ACPI GNVS pointer are not supported. - This hooks up to some soc/intel/common like TCO and ACPI GNVS. GNVS is broken and needs to be fixed separately. It is unknown if TCO is supported. This might require a cleanup in the future.
