The existing mac_read_from_eeprom() is supposed to be used in
conjunction with CONFIG_ID_EEPROM=y. However, when this config option is
enabled, it also expects the do_mac() command to be implemented.
Provide tlv_eeprom's implementation of the do_mac() command. At this
point only the "read" option is supported.
