I've probably asked this before: Does the internal PHY use a different
PHY ID in registers 2 and 3?

yes

reg2: 0x0044
reg3: 0X1500

Copy/paste error, its 1400

So this is not about loading the correct PHY driver. You can already
do this based on the PHY IDs...

This is about selecting which PHY to use. Internal or External?

It is too late when we know the PHY ID.
We need to set a syscon for choosing external/internal PHY.
So we can rely only on DT.
