Provide a generic way for boards to read their serial number from EEPROM at init.
If CONFIG_ID_EEPROM is set, the new serial_read_from_eeprom() function will now be called during the post-relocation part of the board init.
Provided is the tlv eeprom implementation of the above function, making use of the existing, yet never utilized, populate_serial_number(). Boards which use custom logic for interaction with their EEPROMs need to supply their own implementation.

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

Can you please use events for this? Something like EVT_SETTINGS_R ?
See the one recently added for how to do this:
INITCALL_EVENT(EVT_LAST_STAGE_INIT),
