iwlwifi: refactor EEPROM reading/parsing
The EEPROM reading/parsing code is all mixed in the driver today, and the EEPROM is parsed only when we access data from it. This is problematic because the NVM needs to be parsed and that is independent of reading it. Also, the NVM format for new devices will be different and probably require a new parser. Therefore refactor the reading and parsing and create two independent components. Reading the EEPROM requires direct hardware accesses and therefore access to the transport, but parsing is independent and can be done on an NVM blob.
