In case it is defined, call of_get_mac_address for the per-band child node, otherwise try with of_get_mac_address on the main device node and fall back to a random address like it used to be. While at it, add MAC address related properties also for the main node and update example to use EEPROM via nvmem-cells instead of deprecated mediatek,mtd-eeprom property.
