bcmgenet: Unknown PHY model on the Raspberry Pi 400 rev 1.1

A few users have reported that the device fails to start.
Recent boards may be using a different / newer PHY than the one found on the Pi 4 or older 400s.

Nope, it works fine when built from source. There's an issue with the binaries in the RPi-Windows-Drivers repo.

Someone still ran into this issue on a Pi 400 rev 1.1, but this time due to the PHY not being properly identified. After commenting out the check (900a661), the person reported that Ethernet works fine.

Will leave this open until I find out the PHY model on those boards.
