of: of_net: sync of_get_mac_address with Linux for NVMEM support
We don't use of_get_mac_address anywhere, but it can come in handy as a
last resort before barebox generates a random MAC address. With the
existing implementation, that MAC address is written literally into the
DT, so it's mainly useful when barebox is booted with an external device
tree. The kernel implementation adds support for parsing the MAC address
out of a revered mac-address nvmem cell, which is much more prevalent.
Sync the implementation with Linux v5.13 in preparation for using it.
