soc/intel/common: Save Memory DIMM Information in SMBIOS table
Save SMBIOS memory information from FSP MEM_INFO_DATA_HOB in CBMEM.
Add function dimm_info_fill() which populates SMBIOS memory
information from FSP MEM_INFO_DATA_HOB data.
BUG=chrome-os-partner:61729
BRANCH=none
TEST=Build and boot KBLRVP to verify the type 17 DIMM info coming in
SMBIOS table from Kernel command "dmidecode".
