net: mdio: get/put device node during (un)registration
The __of_mdiobus_register() function was storing the device node in
dev.of_node without increasing its reference count. It implicitly relied
on the caller to maintain the allocated node until the mdiobus was
unregistered.
Now, __of_mdiobus_register() will acquire the node before assigning it,
and of_mdiobus_unregister_callback() will be called at the end of
mdio_unregister().
Drivers can now release the node immediately after MDIO registration.
Some of them are already doing that even before this patch.
