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 save state MSR don't work, 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
