Subject: [PATCH v2 04/13] arm64: dts: qcom: lemans-evk: Add nvmem-layout
 for EEPROM

From: Monish Chunara <quic_mchunara@...cinc.com>

Define the nvmem layout on the EEPROM connected via I2C to enable
structured storage and access to board-specific configuration data,
such as MAC addresses for Ethernet.
