of_net: add property "nvmem-mac-address" for of_get_mac_addr() 

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.
