From: Monish Chunara <quic_mchunara@quicinc.com>
Integrate the GT24C256C EEPROM via I2C to enable access to
board-specific non-volatile data.
Also, define an nvmem-layout to expose structured regions within the
EEPROM, allowing consumers to retrieve configuration data such as
Ethernet MAC addresses via the nvmem subsystem.
