From: Fugang Duan <fugang.duan@xxxxxxx> If MAC address read from nvmem cell and it is valid mac address, .of_get_mac_addr_nvmem() add new property "nvmem-mac-address" in ethernet node. Once user call .of_get_mac_address() to get MAC address again, it can read valid MAC address from device tree in directly.
