Subject: [PATCH net-next 1/5] net: dsa: update dsa_of_{probe,remove} to use a device pointer

In preparation for allowing a different mechanism to register DSA switch
devices and driver, update dsa_of_probe and dsa_of_remove to take a
struct device pointer since neither of these two functions uses the
struct platform_device pointer.
