bc2: Enable Board ID field on EEPROM

	- Obtain the Board ID from the EEPROM instead of using the
	  compilation option (excepting customer boards).
	- Enable "boardid" SatR fild access on BC2 boards
	- Modify the BIN header for reading the board ID from EEPROM.
	- When the EEPROM is not present or the information stored
	  in EEPROM is invalid, assign a default board ID = 0, which
	  is a DB board ID for both AC3 and BC2 families.
