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.
Minor nit: this should be properly wrapped.
Yes, I did end up resending the patch a few days later with proper
formatting and superseding this series. I'm very sorry for the confusion.
Resent on the 19th Aug.:

No change apart from the formatting of the commit messages.
