riscv: dts: sifive unmatched: Expose the board ID eeprom
Mark it as read-only as it is factory-programmed with identifying information, and no executable nor configuration: - eth MAC address - board model (PCB version, BoM version) - board serial number Accidental modification would cause misidentification which could brick the board, so marking read-only seem like both a safe and non-constraining choice.
