iwlagn: implement layout-agnostic EEPROM reading
The current EEPROM reading code has some layout assumptions that now turned out to be false with some newer versions of the EEPROM. Luckily, we can avoid all such assumptions by using data in the EEPROM itself, so implement using that. However, for risk mitigation purposes, keep the old reading code for current hardware for now.
