iwlwifi: changing EEPROM layout handling

Browse source 
This patch
1. changes the current EEPROM handling through a single HW struct
layout representation, to more general approach, treating the EEPROM
image as a flat bytes array, handling this image through ops functions
and offsets.
2. Eeprom is dynamically allocated accroding HW type
