This renames all remaining occurrences of "EEPROM" to "art" to
further harmonize the partition labelling in ath79. This will
help to reduce the amount of user-space code and might be
beneficial when code is copy/pasted in the future.
Affected are only devices from Ubiquiti, where the XM board is
already using "art" in ath79.
