board: ti: j721s2: Enable support for reading EEPROM at next alternate address

Browse Source 
J721S2 EVM has EEPROM populated at 0x50. AM68 SK has EEPROM populated at
next address 0x51 in order to be compatible with RPi. So start looking
for TI specific EEPROM at 0x50, if not found look for EEPROM at 0x51.
