AMD AGESA returns DIMM info in SMBIOS format. dimm_info expects the data in SPD format. These methods will be used to update amd_late_init.c so it sets the correct values. BUG=b:65403853 TEST=Built and booted grunt. Methods are not called in this commit. So they were tested with the later commit by verifying the output of dmidecode.
