mediatek: store MAC address in boot partition on Banana Pi R2
Like many boards, the Banana Pi R2 doesn't have permanant storage of its MAC address, and we store the first random one that the kernel generates in order to use it later and at least be consistent. Store it in the FAT boot partition, just as the U7623 board (and others) do. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
