iwl_parse_eeprom_data - parse EEPROM data and return values

: device pointer we're parsing for, for debug only : device configuration for parsing and overrides : the EEPROM data : length of the EEPROM data

This function parses all EEPROM values we need and then returns a (newly allocated) struct containing all the relevant values for driver use. The struct must be freed later with iwl_free_eeprom_data().
