Please do what Russell requested, but also try commenting out the PHY
reset-gpios line in DT which was added by
c720a1f5e6ee8cb39c28435efc0819cec84d6ee2.  It was also commented out
before that change. It could be that gpio controller is missing. Do
you have the driver for the tca6416 in your kernel configuration?
