soc/intel/xeon_sp/cpx: display SystemMemoryMapHob fields 

SystemMemoryMapHob is necessary for SMBIOS type 17 among other things.
It is a fairly large structure, so the pointer to the data instead of
the structure itself, is included in the HOB. Use pointer to
SystemMemoryMapHob structure to interpret SystemMemoryHob HOB body.

Adjust the structure definition to match with CPX-SP ww28 release.

Display more fields to ensure the structure definition is correct.

TEST=Boot DeltaLake server, and check field values of SystemMemoryMapHob
to make sure they are correct:
