mediatek: bpi-r4: store random MAC addresses for the BPi-R4 

Despite coming with multiple I2C EEPROMs supposedly dedicated for that
purpose, the BPi-R4 does not seem to have factory assigned MAC addresses.
Hence, just like for all other BPi boards, store a randomly generated
MAC address on first boot and derive WAN and Wi-Fi MAC addresses from
that as well. Not perfect, but better than random on every boot.
