soc/intel/xeon_sp: Enable SMI handler
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.
