Add HCDB Support for eeprom cache process

While parsing the EEPROMs of the system as part of the EECACHE process
if we detect a part has been replaced, removed, or added then we must
call markTargetChanged to notify hwas to take appropriate actions.
This commit also introduces the new preloaded EECACHE section for simics.
