arm64: zynqmp-dlc21-revA: add mac nvmem cell for gem0
Enable nvmem support for MAC address retrieval from EEPROM for
ethernet@ff0b0000.
Add nvmem-cells and nvmem-cell-names to the GEM0 node, and define a
mac-address@20 cell under the EEPROM node on I2C0.
This allows U-Boot to read the MAC address from EEPROM at offset 0x20.
