Rename populate_serial_number() to a more descriptive
serial_read_from_eeprom() and provide the missing function prototype.
This is useful for boards that wish to read their serial number from
EEPROM at init.

v4: - revert to the approach found in v2
- keep the new serial_read_from_eeprom() name
v3: - restore original function name and make it static
- provide a generic function for reading EEPROM serial number and
wrap it around the existing tlv logic
- move the env var check out of populate_serial_number() and into
the new serial_read_from_eeprom() in order to stay consistent with
the documentation
v2: - rename the function
- move function documentation from .c file to the prototype location
