uhd: Changed mboard_eeprom_t interface, refactored MB EEPROM code

- uhd::usrp::mboard_eeprom_t is now simply a map. Its commit() method
  has no utility being a public API call, because the user never gets
  access to the appropriate I2C object (Minor API breakage)
- The central mboard_eeprom.cpp file was broken up and put into many
  smaller compilation units in every device's implementation folder.
- Renamed some of the constants (e.g. B000_* -> USRP1_*, N100_* ->
  N200_*)
- Removed the N000_* EEPROM code, because, well, you know, there's no
  such device
