My intention is to use the spidev driver in the default board DT for an

The expected way of doing this is to describe whatever was attached via
DT when it's attached - the device is what has the compatible, not some
connector in the middle of the connection. The way you've got things
set up if the device has a driver then they won't be able to instantiate
the driver.
Ok thanks, got it. I will remove the spi device from the board DT and
use an overlay if required. Now I got a reason to learn writing DT
overlays ;)
