board:tricorder: always work with valid eeprom data 

Commit 890880583d introduced EEPROM parsing and
board detection but faild to return a valid tricorder_eeprom struct for backup
case.  When pressing S200 while reading EEPROM we ignore the value. We
returned falsely a tricorder_eeprom struct with uninitialized data which is
just garbage.
Initialize it by zeroing the whole structure.
