soc/intel/apollolake: Update memory HOB info save function

SMBIOS memory HOB produced by glk FSP v52_27 has new structure
members, which are not available in current apl FSP. New FSP-m
header file in https://review.coreboot.org/#/c/20673/ lists new
SMBIOS structure members.

Break memory HOB save routine into different functions for glk
and apl to accomodate new changes.
