kernel: b53: register switch on probe
Currently, the b53 MDIO switch driver registers the switch on
config-init and not on device probe. Because of this, the switch
gets added every time the associated interface comes up.
This commit fixes this behavior by registering the switch on device
probe.
Compile- and run-tested on OCEDO Koala.
