OK, you are right, the property is used here in controller node, however
Linux driver never parsed it. It was never used, so I propose to drop it
from the binding and example. You can mention in commit msg that
spi-max-frequency was not documented thus you drop it from the example.

DTS should be fixed as well. I'll send a patch for it.

Best regards,
