rpi: Copy eth PHY address from fw DT to loaded DT
Some Raspberry Pi 400 boards, specifically rev 1.1, have a different
address for the ethernet PHY device than what is provided by the kernel
DTB. The correct address is provided by the firmware, so we should carry
it over into the loaded device tree so that ethernet works on such boards.
