That's not how this works.  Anyone connecting something to the
SPI header will need to update the DT to reflect whatever they
have connected, if that is something that should be controlled
with spidev then they should add the compatible for that thing
to the driver.  If that is something that has a regular driver
then the regular driver will be used.
