ARM: at91: sama5d27_som1_ek: populate MAC address from EEPROM
With the latest NVMEM enhancements merged, barebox networking core now
always consults NVMEM cells referenced in the network controller
device tree node before it falls back to randomizing a new address.
The SAM5D27-SOM1 has a 256 byte EEPROM, which holds a MAC address in its
last 6 bytes. Describe this in the device tree, so boards using the SoM
will get an unique MAC address assigned and fixed up into the kernel
device tree. This change can be dropped again when/if the change is
submitted and applied upstream.
