net: dsa: microchip: ksz8: on exit hold switch in reset

When the switch is probed, the last step is to register with the dsa subsystem.
However, the dsa subsystem might not be initialized yet and will return
EPROBE_DEFER. That also means the probing of the switch has to be deferred.
Because the ksz8863 switches by default and we have to guarantee that we
can keep both ports seperated, the switch must be put back into reset.
